Title:
qemu 2.7 / iPXE crash
Status in QEMU:
Fix Committed
Bug description:
I am running Arch linux
vanilla 4.7.2 kernel
qemu 2.7
libvirt 2.2.0
virt-manager 1.4.0
Since the upgrade from qemu 2.6.1 to 2.7 a few days ago. I'm no longer
able to PXE boot at all. Everything else appears to function normally.
Non PXE booting and everything else is perfect. Obviously have
restarted everying etc. Have tried the various network drivers also.
This occurs on domains created with 2.6.1 or with 2.7
When I choose PXE boot, the machine moves to a paused state (crashed)
immediately after the 'starting PXE rom execution...' message appears.
Reverting to qemu 2.6.1 package corrects the issue.
The qemu.log snippet follows below.
I'm not sure how to troubleshoot this problem to determine if it's a
packaging error by the distribution or a problem with qemu/kvm/kernel?
Any help would be much appreciated - Thanks,
Greg
