[Qemu-devel] [Bug 1123975] Re: QEmu 1.3.90 cannot restore a 1.1.2 live snapshot |

This sounds pretty much like a prob with video ram size. In 1.1.x, we
had video ram of 8Mb, in 1.3 it is 16Mb... should this be a problem, to
come from smaller to larger size?
Besides that, debian uses almost unmodified qemu, so the same prob
should exist for upstream qemu too.
But at any rate, I never recommended any sort of cross-version migration
as in practice, despite countless efforts spent to make it to work, it
almost always does NOT work.
Thanks,

Title:
QEmu 1.3.90 cannot restore a 1.1.2 live snapshot
Status in QEMU:
New
Bug description:
I have upgraded to QEmu 1.3.90 (Debian 1.4.0~rc0+dfsg-1exp) but now
when I try to restore a live snapshot made in QEmu 1.1.2 (Debian
1.1.2+dfsg-5) I get the following message:
virsh # snapshot-revert fgtbbuild wtb
error: operation failed: Error -22 while loading VM state
I have test VMs with live snapshots coreresponding to different
testing configurations. So I typically revert the VMs in one of the
live snapshots and run the tests. It would be pretty annoying to have
to recreate all these live snapshots any time I upgrade QEmu.
