| macjl | Hello | 09:57 |
|---|---|---|
| macjl | I'm trying to install Unbuntu in LPAR | 09:57 |
| macjl | But facing problems with VLAN tagging | 09:57 |
| macjl | The installer don't ask me if I use VLAN, so the network does'nt work... | 09:58 |
| macjl | Anyone know how to net install ubuntu on s390x arch with VLAN tagging? | 09:59 |
| xnox | macjl, you have two options | 10:07 |
| xnox | macjl, return to main menu ("<") | 10:07 |
| xnox | change debconf priority to medium | 10:07 |
| xnox | then it should ask you to use vlan, but that may or may not work. | 10:07 |
| xnox | i typically "go through the motions up to ssh client password setup" | 10:08 |
| xnox | then return to main menu | 10:08 |
| xnox | drop to shell | 10:08 |
| xnox | and bring up vlan network by hand, e.g. | 10:08 |
| xnox | ip link set dev encc000 up | 10:08 |
| xnox | ip link add link encc000 name encc000.2654 type vlan id 2654 | 10:08 |
| xnox | ip addr add 10.245.237.7/24 brd 10.245.237.255 dev encc000.2654 | 10:08 |
| xnox | ip link set dev encc000.2654 up | 10:08 |
| xnox | ip route add default via 10.245.237.1 | 10:09 |
| xnox | echo nameserver 10.245.237.1 >> /etc/resolv.conf | 10:09 |
| xnox | .. | 10:09 |
| xnox | adjust as needed. | 10:09 |
| xnox | you would then have to bring up network by hand again in the installed system, and adjust /etc/network/interfaces | 10:09 |
| xnox | work is in progress to improve vlan network support. Do let me know your experience with debconf medium priority that does ask for vlan network tag. | 10:10 |
| macjl | Thans, I'll try! | 10:13 |
| xnox | macjl, no problem. =) | 10:13 |
| Bercik | It's good to see people alive on s390* channels :) | 11:55 |
| xnox | Bercik, yeah =) slowly picking up. | 12:18 |
| Bercik | I remember idling +/- 9 months on hercules channel. Not even one word :) | 12:19 |
| xnox | hehe | 12:19 |
| xnox | honestly i have tried hercules, but did not manage to boot anything in it =( | 12:19 |
| Bercik | I did | 12:19 |
| Bercik | but not with ubuntu ;( | 12:19 |
| Bercik | nor modern distros (RHEL 7, SLES 12). | 12:20 |
| xnox | yeah, cause ubuntu needs transactional memory and like zEC12 or better cpu | 12:20 |
| xnox | i don't think hercules has emulation for that | 12:20 |
| Bercik | I tried newest 4.0 | 12:20 |
| xnox | i wish qemu had system emulation on other platforms, but that's not in for same reasons arm64 foreign emulation is not there | 12:20 |
| xnox | hm, i did not try 4.0 from github, right? | 12:21 |
| Bercik | yup, | 12:22 |
| Bercik | It runs debian 8 with no problems. Same for my rusty z/OS 1.10 | 12:22 |
| xnox | https://github.com/hercules-390/hyperion/issues/39 | 12:23 |
| xnox | we need that for ubuntu | 12:23 |
| Bercik | Depends on my CPU config. After IPL it ends up with "you need more recent hardware" or Wait State | 12:24 |
| Bercik | xnox, --enable-interlocked-access-facility-2=yes|no | 12:35 |
| Bercik | enable/disable Interlocked Access Facility 2 | 12:35 |
| Bercik | (default yes) | 12:35 |
| Bercik | this is mentioned multiple times, when talking about Linux IPL, and this new version seems to has it. | 12:35 |
| xnox | no idea. i just know that both kernel and glibc use transactional memory on ubuntu (and other modern distros too) | 12:36 |
| xnox | and that needs transactiona-execution facility | 12:36 |
| xnox | i don't know what this interlocked access facility is, and/or if transactional memory/execution is implemented using above in hercules | 12:36 |
| macjl | For infomation, with debconf priority set to medium, I was able to choose a VLAN ID | 14:36 |
| macjl | But after installation, the configuration was not ste in /etc/network/interfaces | 14:37 |
| macjl | I had to set it up manually | 14:37 |
| xnox | macjl, ack. thanks. | 14:58 |
| xnox | will investigate and will try to fix that up. | 14:58 |
| xnox | macjl, if you wish you can open a bug report about that with $ ubuntu-bug debian-installer | 14:59 |
| xnox | or open one on launchpad manually against ubuntu project, debian-installer package, and attach logs from /var/log/installer | 14:59 |
| xnox | if you can/allowed to share those. | 14:59 |
| macjl | I'll see if I can | 15:04 |
| macjl | Now I'm trying to make bonding work with vlan.... | 15:04 |
| xnox | macjl, =))))) it should work, i try to avoid fiddling with things like that, and just defer it to infrastructure team =) | 15:08 |
| macjl | It worked with VLAN + bonding. I've just moved a VM from IBM KVM to Ubuntu (offline) with no problems :) | 15:55 |
| macjl | It doesn't seem to work with live migration because of a SELinux problem : | 15:57 |
| macjl | error: unsupported configuration: Unable to find security driver for model selinux | 15:57 |
| xnox | macjl, right. in ubuntu we support live migration among our hypervisors (e.g. lxd to lxd, qemu to qemu) | 16:11 |
| xnox | i don't know if it's possible to move things form z/KVM to Ubuntu live. | 16:11 |
| xnox | macjl, could you open a bug report about that? because surely we should be able to translate selinux model to apparmor (which is what used to protect qemu on ubuntu) and/or give option to ignore selinux context for migration (sub-optimal, but better than failing outright) | 16:12 |
| xnox | maybe we can enable selinux in relevant parts of the stack to make migrations work too. | 16:12 |
| xnox | if you add tag "s390x" to the bug report, I will notice it and can route it appropriately to the right ubuntu teams | 16:13 |
