In libvirt log file I can see:
error : qemuDomainDefineXML:6312 : block copy still active: domain has
active block job
Libvirt is 1.2.7 version, linux system is Debian Wheezy
Please, what does it mean ?
It means, according to libvirt, there's an unfinished `blockcopy` (Copy
a disk backing image chain to destination ) operation.
If you can find the associated libvirt guest name, you can try the
below maybe.
For the Nova libvirt guest that you're trying to create a snapshot of,
find the location of its current block device:
$ virsh domblklist instance-YYYYYYYYY
Then check if there are active block operaations for that disk:
$ virsh blockjob instance-YYYYYYYYY /path/to/libvirt/disk/ --info
If there is any operation and if it is a test environment, you can
run the below to abort the block operation in progress:
$ virsh blockjob instance-YYYYYYYYY /path/to/libvirt/disk/ --abort.
Please the man page of `virsh` for more details.
Thank for your response, I'm quite new on libvirt...
1) virsh blockjob ... -info gave me an empyt list
2( virsh blockjob ... -abort gave me this error: error: Requested operation
is not valid: another job on disk 'vda' is still being ended....
..but what ?
Seems like you're hitting an old bug[1] where 'blockcopy' (or
'blockcommit') missed to execute a cleanup routine which destroys a
reference to the active block operation -- resulting in the error you're
seeing when you attempted to 'abort' the block operation manually.
This bug is fixed in libvirt-1.2.8 and above. I see you're using
libvirt-1.2.7, if you can update libvirt in your environment, that
should fix your issue.
[1] https://bugzilla.redhat.com/show_bug.cgi?id=1135169 -- blockcopy job
was cancel by "CTRL+C" while it show there still be one block job in
background
Ok, thank you.
I'll update libvirt as soon as possible, as I can see there is an update
on my system for libvirt...
