[pve-devel] vm migration source vm crash, with qxl , qemu 2.7 -> qemu 2.9

[Alexandre DERUMIER]

mmm, seem to be random. (sometime it's work, sometime crash, with/without qemu 2.7 - 2.9)

I have seen bug report on qemu mailing list, seem to be related to spice driver in windows 10 too.

Objet: [pve-devel] vm migration source vm crash, with qxl ,	qemu 2.7 -> qemu 2.9

Hi, 

I have tested vm live migration with qxl/spice enabled, from proxmox 4.4 (qemu 2.7) to proxmox 5.0 (qemu 2.9), 

the source vm is crashing during the migration: 


kvm: hw/display/qxl.c:2138: qxl_pre_save: Assertion `d->last_release_offset < d->vga.vram_size' failed. 
Aborted 


It's working fine between 2 proxmox 4.4 nodes (both qemu 2.7)
