Subject: [PATCH] qemu_migration: Store original migration params in status XML
|
|
|
|
We keep original values of migration parameters so that we can restore
|
|
them at the end of migration to make sure later migration does not use
|
|
some random values. However, this does not really work when libvirt
|
|
daemon is restarted on the source host because we failed to explicitly
|
|
save the status XML after getting the migration parameters from QEMU.
|
|
Actually it might work if the status XML is written later for some other
|
|
reason such as domain state change, but that's not how it should work.
