| danstoner | eye of gnome does not respect the system umask. | 15:14 |
|---|---|---|
| danstoner | seems to be hard-set to owner has rw. | 15:15 |
| danstoner | exposed when rotating an image and then saving. | 15:15 |
| danstoner | discovered when my wife was unable to view a random number of images on our home fileserver. | 15:15 |
| danstoner | this in 10.04 LTS | 15:24 |
| danstoner | er... seems to actually be a Gnome thing, not limited to eog. | 15:38 |
| danstoner | Maybe setting umask in /etc/profile or each users .profile works. | 15:44 |

| DammitJim | do you guys think that performance for a virtual machine could be improved if you had a separate hard drive for it? | 15:45 |
| danstoner | not if the separate hard drive is USB. | 15:46 |
| danstoner | Is this KVM / libvirt ? | 15:46 |
| DammitJim | virtualbox | 15:48 |
| DammitJim | I would buy a separate hard drive bay for my precision laptop | 15:48 |
| danstoner | If i/o contention is the issue, then adding another drive might help. But if it is slow because of some other reason, might not help. | 15:49 |
| danstoner | Won't hurt. KVM gets better performance off "raw" partitions rather than file-based images stored on a file system. | 15:51 |
| danstoner | Virtual Box I don't know. | 15:51 |
| DammitJim | danstoner, what do you mean by raw partitions? like if I just used /dev/sdb5 for that virtual machine? | 16:18 |
| DammitJim | I don't know if I can do that with virtualbox | 16:18 |
| danstoner | DammitJim: yes, a raw block device (could be a partition, a logical volume, ...) | 16:19 |
| danstoner | I don't think virtualbox io sucks in general, so it might be fine keeping images on a filesystem. | 16:20 |
| danstoner | What are the performance issues you notice that led you to think adding a drive might help? | 16:21 |
| DammitJim | I just see this little hard drive light on ALL the time now that the VM is running | 16:21 |
| DammitJim | and everything on my host has slowed down, but CPU and memory doesn't look pegged | 16:21 |
| danstoner | using any swap space? | 16:22 |
| DammitJim | no | 16:22 |
| danstoner | what guest OS? | 16:22 |
| DammitJim | 7 | 16:22 |
| danstoner | Windows 7? | 16:22 |
| DammitJim | yes | 16:23 |
| danstoner | How much RAM did you give to the guest? | 16:23 |
| danstoner | How much RAM in the host computer (your workstation)? | 16:23 |
| DammitJim | 2gb | 16:24 |
| DammitJim | 2gb | 16:24 |
| danstoner | ? virtualbox let you give the guest 2 GB? | 16:25 |
| DammitJim | yeah, why? | 16:25 |
| danstoner | with only 2 GB of real RAM in the system? | 16:25 |
| DammitJim | oh no, I have 4GB total, I'm sorry | 16:26 |
| danstoner | ah. | 16:26 |
| danstoner | any other vms running at the same time? | 16:26 |
| DammitJim | no | 16:26 |
| danstoner | Your Windows 7 is already infected with malware. ;) | 16:28 |
| DammitJim | lmao | 16:28 |
| DammitJim | I actually wish for that | 16:28 |
| DammitJim | maybe it doesn't help that I have playonlinux running with powerpoint | 16:29 |
| danstoner | Does it ever settle down? Windows does a bunch of stuff in the background but I would expect idle system would not keep the hard drive going. | 16:29 |
| DammitJim | I know it will, I mean.. I want to be able to let Visual Studio compile it's thing while I'm on LInux doing my thing | 16:29 |
| DammitJim | that's why I thought another hard drive would help... then I keep them separate | 16:30 |
| danstoner | There is a good chance it will help, but depends on where the bottleneck really is. | 16:31 |
| danstoner | Are all of the files the windows vm uses local to the machine (e.g. not talking to a fileserver somewhere)? | 16:34 |
| DammitJim | right now... all local | 16:34 |
| danstoner | If I had to solve your issue without spending money, I would try changing the virtual storage controller. | 16:36 |
| danstoner | If I could bill someone for the hd, I'd buy the hd. | 16:36 |
| danstoner | Here is (possibly) how to use raw disk: | 16:37 |
| danstoner | http://www.virtualbox.org/manual/ch09.html#rawdisk | 16:37 |
| danstoner | I always used "fixed-size images" rather than dynamically expanding images. | 16:39 |
| danstoner | http://www.virtualbox.org/manual/ch05.html | 16:39 |
| DammitJim | interesting... this time I decided to go with a dynamically expanding image | 16:42 |
| danstoner | KVM also has really crummy performance with disk images on ext4 filesystem. So if you get a second drive, use bare storage or a better filesystem. | 16:43 |
| danstoner | You could also try changing i/o controller from SCSI to IDE or vice versa. | 16:45 |
| DammitJim | the controller is a SATA controller now | 16:46 |
| DammitJim | thanks for the link, though... looks promising to do a raw disk | 16:47 |
| DammitJim | I just took away 1 CPU from the VM... let's see how the host behaves | 16:49 |
| DammitJim | like I said... I don't care as much as the Windows VM as I do of the linux host | 16:49 |
