I am trying Libvirt synchronous hooks and I would like to ask a
question. I would like to use the machine start (qemu+kvm) hook to
set up the storage for the machine. I already mentioned my setup in
this mailing list but for now it is only important that VM storage
is a md raid constructed from iSCSI disks. The VM's config is using
simple file device:
<disk type='file' device='disk'>
<driver name='qemu' type=''/>
<source
file='/dev/disk/by-id/md-uuid-e464a51e:f61e98b4:bfe78010:bc810f04'/>
<target dev='vda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x05'
function='0x0'/>
</disk>
Stopping the array from stop hook works perfectly however it seems
that on the startup the storage is checked before the hook is
executed. At least I do get errors that the storage file
(/dev/disk/by-id/md-uuid-....) does not exist and my hook is not
called.
I would say that I am hooking on wrong places that I should hook on
storage startup/shutdown but as far as I know there are no hooks for
storage drivers. Are there any plans in this area? Or is there any
other way how to do it that I do not see?
Old mail, but stll valid :-)
Yes adding more hooks as need arise sounds fine to me, especially
around storage/interface setups.
