Re: [libvirt-users] Unable to autostart storage pool.
2010/8/27 Sharad Mishra <snmishra(a)us.ibm.com>:
Following xml file was used to create storage pool using 'virsh
pool-create
<xml>'
<pool type='dir'>
<name>my-diskpool</name>
<uuid>2fbc894e-7619-6cda-a33c-b27fae5fbe8b</uuid>
<capacity>136024670208</capacity>
<allocation>11416657920</allocation>
<available>124608012288</available>
<source>
<host name='localhost'/>
</source>
<target>
<path>/var/lib/libvirt/images</path>
<permissions>
<mode>0700</mode>
<owner>0</owner>
<group>0</group>
</permissions>
</target>
</pool>
The command succeeds and a pool is created -
# virsh pool-list --all
Name State Autostart
-----------------------------------------
my-diskpool active no
When I try to set it up for autostart, I get -
# virsh pool-autostart my-diskpool
error: failed to mark pool my-diskpool as autostarted
error: invalid argument in pool has no config file
Why is it failing to autostart?
/etc/libvirt/storage has no xml file.
'virsh pool-create <xml>' creates a transient pool, that has no
persistent config on disk. Such a pool cannot be autostarted, because
it's gone when you call pool-destroy on it.
In order to have an autostartable pool you need to 'virsh pool-define
<xml>' the pool, this creates a pool with a persistent config in
/etc/libvirt/storage.
