Version-Release number of selected component (if applicable):

libguestfs-tools-c-1.20.9-1.fc18.x86_64
libguestfs-tools-1.20.9-1.fc18.x86_64
libguestfs-1.20.9-1.fc18.x86_64

Host is Fedora 18.
Guest is Fedora 18.

How reproducible:

Unknown.
Comment 1 Richard W.M. Jones 2013-07-25 08:03:45 UTC 
The cause of this is because the source VM has two disks,
with the volume group spread over these disks.

virt-resize does not currently support guests with multiple
disks, although it should be fixed to do this.
Comment 2 Alex Regan 2013-07-26 03:11:33 UTC 
Hi, I've created a paste with more details:

http://pastebin.com/3T9dt8RH

I had to transfer the guest image to a fedora15 host and create the new vm with the guest image using "virsh create" because I couldn't do it on the production fedora18 system.

The guest is fedora18 x86_64.

virt-resize appears to have the same problem, however.
Comment 3 Alex Regan 2013-07-26 03:16:25 UTC 
I should add the version of libguestfs being used on fc15:

# rpm -qva|grep libguest
libguestfs-tools-c-1.10.12-1.fc15.x86_64
libguestfs-1.10.12-1.fc15.x86_64
libguestfs-tools-1.10.12-1.fc15.x86_64

And the df output from the guest:

# df -h
Filesystem                Size  Used Avail Use% Mounted on
devtmpfs                  7.9G     0  7.9G   0% /dev
tmpfs                     7.9G     0  7.9G   0% /dev/shm
tmpfs                     7.9G  807M  7.1G  11% /run
tmpfs                     7.9G     0  7.9G   0% /sys/fs/cgroup

/dev/mapper/propserv-home  222G  215G  7.5G  97% /home

And the disk sections from the vm:

    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2'/>
      <source file='/var/backup/propserv-backup-072113.img'/>
      <target dev='vda' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
    </disk>
    <disk type='file' device='disk'>

Comment 5 Alex Regan 2013-10-01 16:42:03 UTC 
Is there any update on this?
Comment 6 Richard W.M. Jones 2013-10-01 16:43:59 UTC 
No, it needs some development work upstream to fix it.  ie patches
are welcome!  It's not an especially hard fix.
Comment 7 Alex Regan 2014-07-26 20:14:56 UTC 
Just wondering if there's any update on this? I've upgraded the host to fedora20, hoping that now includes the fixes necessary to grow an LVM partition...
Comment 8 Richard W.M. Jones 2014-07-26 20:17:53 UTC 
No I'm afraid there has still been no development work to
fix this (virt-resize on 2 disks).
Comment 9 Red Hat Bugzilla 2025-10-17 00:10:03 UTC 
This product has been discontinued or is no longer tracked in Red Hat Bugzilla.
Comment 10 Alasdair Kergon 2025-10-17 12:52:13 UTC 
Reopening because Virtualization Tools has not been discontinued.
