Subject: xen: ignore live parameter from xen-save-devices-state
|
|
|
|
References: bsc#1079730, bsc#1101982, bsc#1063993
|
|
|
|
The final step of xl migrate|save for an HVM domU is saving the state of
|
|
qemu. This also involves releasing all block devices. While releasing
|
|
backends ought to be a separate step, such functionality is not
|
|
implemented.
|
|
|
|
Unfortunately, releasing the block devices depends on the optional
|
|
'live' option. This breaks offline migration with 'virsh migrate domU
|
|
dom0' because the sending side does not release the disks, as a result
|
|
the receiving side can not properly claim write access to the disks.
|
|
|
|
As a minimal fix, remove the dependency on the 'live' option. Upstream
|
|
may fix this in a different way, like removing the newly added 'live'
|
|
parameter entirely.
|
|
|
