| jamespage | zul, jdstrand: is it possible to put the libvirt templates generates for instances into complain mode? trying to generate some updates for using hugepage memory | 10:38 |
| === kickinz1 is now known as kickinz1|lunch | ||
| zul | jamespage: yes but i forgot how | 12:20 |
| === kickinz1|lunch is now known as kickinz1 | ||
| jdstrand | jamespage: yes, modify /etc/apparmor.d/libvirt/TEMPLATE.qemu to have "profile LIBVIRT_TEMPLATE flags=(complain) {" | 13:12 |
| jamespage | jdstrand, awesome - thankyou | 13:12 |
| jdstrand | np | 13:26 |
| jamespage | jdstrand, I've probably learn't and forgetten this already but is there a nice way to parse the complain entires into an profile update? | 13:37 |
| jdstrand | jamespage: there is a program called aa-logprof, yes, but it isn't smart enough to know to update the template and it may have trouble finding the vm profile in /etc/apparmor.d/libvirt | 13:51 |
| jdstrand | jamespage: if you were keen on doing that, you could try passing the '-d' directive to logprof, then do a diff between the template and the profile | 13:51 |
| jdstrand | but, handcrafted in this case is probably faster | 13:52 |
| jamespage | jdstrand, ack | 13:52 |
| jamespage | jdstrand, and do we have a nice mechanism for providing local profile updates for the generated profiles? | 13:53 |
| jamespage | I was trying to figure it out but got stuck... | 13:53 |
| jdstrand | jamespage: if you want all VMs to pick up the change, you can modify /etc/apparmor.d/abstractions/libvirt-qemu. if you want only a single vm to have the change, you can modify /etc/apparmor.d/libvirt/libvirt-<domain uuid> (note, *not* the one with the .files extension) | 13:55 |
| jamespage | jdstrand, ok - ta | 13:55 |
| jdstrand | np | 13:55 |
| jdstrand | jamespage: I think you're set now, but fyi, http://wiki.apparmor.net/index.php/Libvirt | 13:56 |
| jdstrand | I see it needs a couple updates | 13:56 |
| * jdstrand does so | 13:57 | |
| jamespage | jdstrand, how does that look - http://paste.ubuntu.com/12071349/ ? | 14:20 |
| jamespage | I suspect the top two rules are generically applicable - the third is dependency on where hugepages gets mounted | 14:20 |
| jdstrand | the rules are written well for the denials. however, I think they are too lenient | 14:22 |
| jdstrand | so, qemu only complained about the dir for cpu, so this might be better: | 14:23 |
| jdstrand | /sys/devices/system/cpu/ r, | 14:24 |
| jdstrand | I think this would be better for node: | 14:24 |
| jdstrand | /sys/devices/system/node/ r, | 14:24 |
| jdstrand | /sys/devices/system/node/node[0-9]*/** r, | 14:25 |
| jdstrand | actually, even better | 14:25 |
| jdstrand | /sys/devices/system/node/node[0-9]*/meminfo r, | 14:25 |
| jdstrand | as for the hugepages mount point, there is already this rule in libvirt-qemu: | 14:26 |
| jdstrand | owner "/run/hugepages/kvm/libvirt/qemu/**" rw, | 14:26 |
| jdstrand | it that not enough? (I feel there was a bug on this) | 14:26 |
| jdstrand | https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1001584 | 14:27 |
| ubottu | Launchpad bug 1001584 in libvirt (Ubuntu) "libvirt-bin support for hugepages: apparmor needs a rule for hugetlbfs" [Medium,Expired] | 14:27 |
| jdstrand | https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1250216 | 14:28 |
| ubottu | Launchpad bug 1250216 in libvirt (Ubuntu Saucy) "apparmor policy prevents using hugepages" [High,Fix released] | 14:28 |
| jdstrand | that last bug suggests that virt-aa-helper should be updated to generate the paths. is the mountpoint expressed in the domain xml? | 14:29 |
| jdstrand | jamespage: ^^ | 14:29 |
| jamespage | jdstrand, reading | 14:29 |
| jdstrand | jamespage: here is a cleaned up summary of the above: http://paste.ubuntu.com/12071434/ | 14:32 |
| jamespage | jdstrand, thanks | 14:35 |
| jamespage | jdstrand, so for the owner "/run/hugepages/kvm/libvirt/qemu/**" rw, bit, I just need to make sure that hugepages is being mounted in the correct location I think | 14:36 |
| jdstrand | right, that is what I was thinking | 14:36 |
| jamespage | # /run/hugepages/kvm/ | 14:36 |
| jdstrand | I don't know what the domain xml looks liek for hugepages, but if it says where they are mounted, then virt-aa-helper (the thing that stitches together the template, the uuid and uuid.files files) can be made to add the paths to the .files file automatically | 14:38 |
| jdstrand | if it isn't in the domain xml, it would require a bit more work I think | 14:38 |
| Kgirthofer | so someh ow I created a file called \ | 18:00 |
| Kgirthofer | how do I delete it | 18:00 |
| Kgirthofer | when I put it in rm it just says missing operand | 18:00 |
| Kgirthofer | n.m | 18:01 |
| Kgirthofer | rm \\ | 18:01 |
| Kgirthofer | :) | 18:01 |
| fellayaboy | whats the new package for dhcp server...i tried sudo apt-get install isc-dhcp-server on ubuntu server 15.04 but says cant find package..also tried sudo apt-cache search dhcp didnt find anything about server | 18:35 |
| qman__ | fellayaboy: http://packages.ubuntu.com/vivid/isc-dhcp-server | 18:41 |
| qman__ | your sources must not be correct | 18:41 |
| fellayaboy | think i need to do apt-get update | 18:41 |
| fellayaboy | let me also check apt/sources.list | 18:42 |
| fellayaboy | thanks qman that solved it | 18:45 |
| Danskmand | Howdy :-) - I want to install syslog-ng on my servers using puppet....Now I see that syslog-ng has a open bug with this since ano 2006 - cannot install syslog-ng because it has unmet dependencies ( syslog-ng : Depends: syslog-ng-core (>= 3.5.3), ....) | 19:10 |
| Danskmand | I can install syslog-ng by first installing syslog-ng-core and then install syslog-ng. But thats not easy in puppet.... | 19:10 |
| sarnold | Danskmand: how are you trying to install it? apt-get install <foo> ought to handle all the deps for you without trouble. | 19:12 |
| Danskmand | sarnold: Yeah, I know - but running "apt-get install syslog-ng" results in "The following packages have unmet dependencies:" | 19:14 |
| Danskmand | " | 19:14 |
| Danskmand | "syslog-ng : Depends: syslog-ng-core (>= 3.5.3)" | 19:16 |
| Danskmand | (3 more depends, 5 recommends) | 19:16 |
| Danskmand | e: Unable to correct problems, you have held broken packages | 19:16 |
| sarnold | that's interesting, never seen that before | 19:17 |
| sarnold | try this: dpkg --get-selections | grep -v install | 19:17 |
| Danskmand | When I then do a "apt-get install syslog-ng-core" it installs that and when I then repeat the "apt-get install syslog-ng" it installs without a problem ! | 19:19 |
| Danskmand | So it is really that syslog-ng-core ,,,, | 19:19 |
| Danskmand | The .v results into - nothing - | 19:20 |
| sarnold | hmm. I don't have any held packages on my systems, I assumed the 'install' would go away if it were held.. maybe try dpkg --get-selections | grep held or | grep hold ? | 19:22 |
| Danskmand | Yeah, - nothing - | 19:23 |
| Danskmand | OKay....have installed a new ubuntu-Server as a vm @ home and run "apt-get install syslog-ng" - there it will install is without any problems ! - the new system is on 15.04 - the problem-server is on 14.04 LTS.... | 19:30 |
| sarnold | I suspect a brand-new 14.04 would also work fine, there's something strange on your existing system.. | 19:30 |
| Danskmand | I see theres a 14.04.3 release - how can I find out the release I am running down to the "3"-number ? | 19:36 |
| Danskmand | Forget it - I overread it - I have a 14.04.1 release running... | 19:37 |
| Danskmand | How do I upgrade to 14.04.3 release ? | 19:38 |
| OerHeks | sudo apt update && sudo apt full-upgrade | 19:39 |
| sarnold | Danskmand: full details here https://wiki.ubuntu.com/Kernel/LTSEnablementStack | 19:39 |
| Danskmand | I just dont wann upgrade away from the LTS-release... | 19:40 |
| sarnold | the 14.04.1 kernel will be supported for the full five years; if you upgrade to 14.04.3 you'll need to upgrade to the 14.04.5 kernel in august 2016. | 19:41 |
| Danskmand | Hmm....okay, so upgrading is not the solution if I dont wanna loose the LTS and wanna solve my problem.... | 19:44 |
| sarnold | just keep running apt-get update && apt-get -u dist-upgrade on a regular basis | 19:45 |
| === zerick_ is now known as zerick | ||
| Danskmand | Running the apt-get dist-upgrade looks to me like I will leave the LTS-path.... | 20:03 |
| Danskmand | Which I cannot... | 20:03 |
| sarnold | the usual 'upgrade' command refuses to install new packages, which means e.g. kernel updates never happen. dist-upgrade can install new packages, so you'll get new kernel packages. it only changes the actual distribution if you modify the 'trusty' to 'vivid' or 'wily' in your /etc/apt/sources* files | 20:06 |
| === markthomas is now known as markthomas|away | ||
| Danskmand | Okay...running dist-upgrade right now.... | 20:12 |
| Danskmand | Lets hope we have a server afterwards.... | 20:12 |
| Danskmand | We have a problem with our servers hdd-controller of some kind... | 20:13 |
| sarnold | you should, i've run apt-get dist-upgrade a few thousand times in 15 years and only had two or three problems, back in the days when I ran debian unstable, and that kind of thing was expected. :) | 20:13 |
| Danskmand | Yeah, and I can still choose the old kernel at boot... | 20:14 |
| Danskmand | Its a known problewm with the hp....380 Servers... | 20:16 |
| Danskmand | Ooops ! - No more system I think ! | 20:26 |

| sarnold | Danskmand: did you need to build an out-of-tree kernel module to mount your storage array? | 20:30 |
| Danskmand | NOw my prompt is "initramfs"..... | 20:30 |
| Danskmand | Hmmm...dont know - wasnt there when it was built..... | 20:30 |
| sarnold | Danskmand: maybe you need to rebuild your initramfs with a specific kernel module to allow mounting the array? | 20:31 |

| Danskmand | Sh**.....Can you help me on this ? | 20:39 |
| Danskmand | Please ? | 20:39 |
| sarnold | you need to install kernel updates; there's just no way around that. You've got to figure out how to make that system reliable enough to reboot whenever you need with a new kernel. | 20:39 |
| Danskmand | So in other words, the system is wrecked now - I need to reinstall .... | 20:41 |
| Danskmand | No way back, right ? | 20:41 |
| sarnold | i'm sure there's a way forward | 20:41 |
| sarnold | i've just never had one of those machines | 20:41 |
| sarnold | there's a note that the dynamic smart array needs to be disabled on one specfic generation, but I don't know if that's something that would affect you or not http://www.ubuntu.com/certification/hardware/201401-14512/ | 20:42 |
