Subject: [PATCH] block: bugfix: Don't pause vm when NOSPACE EIO happened
|
|
|
|
When backend disk is FULL and disk IO type is 'dataplane',
|
|
QEMU will pause the vm, and this may cause endless-loop in
|
|
QEMU main thread if we do the snapshot merge now.
|
|
|
|
When backend disk is FULL, only reporting an error rather
|
|
than pausing the virtual machine.
