[SOLVED]libvirt: Unable to use volume group for storage - write errors

railmaniac · 2012-11-07 15:46:38

Hi,

I'm using a volume group as a storage pool in libvirt. I'm using libvirt through the virt-manager GUI.

If I create a disk on the volume group, it gets created successfully (below labelled 'quantal'):

disk

However, when I start to install the guest, as soon as the step to write to the disk comes up, I start getting write errors:

guest

A dmesg output on guest:

dmesg

This does not happen if I use the default storage /var/lib/libvirt/images. There the write happens successfully and my VM is up and running. Only for the volume group.

Does anyone know why this is happening? The Arch wiki claims that selinux won't let you have guests anywhere other than /var/lib/libvirt/images by default, but as far I know I haven't installed selinux. Any help would be appreciated.

What follows below is a dump of journalctl for the relevant duration. I don't know if this is useful (it's huge though). Please do recommend what other information I can provide to debug this.

Thanks.

Just a few updates on this:

Nov 07 20:23:41 core kernel: Buffer I/O error on device dm-1, logical block 557858
Nov 07 20:23:41 core kernel: lost page write due to I/O error on dm-1

Apparently this sort of errors come when the drive is failing. My laptop is fairly new and I'm pretty sure the drive is not failing. Just to be sure I tried creating a logical volume and formatting it into ext4 the normal way - all the while keeping a 'journalctl -f' running on another terminal. Went without a hitch, no errors about drive failing.

- I considered the possibility that the ISO got corrupt somehow while transferring from my old computer to an external drive and the external drive to my laptop (because another ISO wouldn't even boot). I downloaded a DSL iso, checked its MD5 and ran it. Same result.

- Another time I got a warning about qemu-kvm running as root. I started a VM on an ubuntu box and found that, sure enough, qemu-kvm was not running as root. I downloaded the libvirtd.deb file from Ubuntu repositories and looked at the postinst functions and created users and groups accordingly. I then modified the /etc/libvirt/qemu.conf file and restarted libvirtd. Once again, the VMs on /var/lib/libvirt/images ran without a hitch, but I couldn't write to a logical volume. Same errors in the journal.

I'm tired of this. I became desperate enough to have a stupid workaround for this. My / is btrfs. I created a logical volume and did a btrfs device add on it. Now my /var/lib/libvirt/image is magically larger. If I can't work this out I'll just add huge chunks of my volume group to my btrfs.

I know it's probably a stupid way of doing things, but hey what can I do?

Hi,

This seems to be solved now. I think the culprit was the btrfs which also caused other problems with qemu. This is working fine with ext4 root.
