I upgraded app-emulation/qemu-kvm from v0.15.1-r1 to v1.0-r3 today. This also pulled in sys-apps/vgabios-0.6c-r1. The emerge for both was successful, and etc-update, depclean, revdep-rebuild showed nothing. I didn't change anything inbetween, everything should function the same as before. But after the upgrade, when trying to start a VM, basically nothing happens. It just terminates instantly. I dug and found if this only breaks if I set the bios to vga or vmvga (which is all I use today). cirrus/qxl/xen continue to work fine. I see this message in /var/log/libvirt/qemu/[vm].log: qemu-system-x86_64: /var/tmp/portage/app-emulation/qemu-kvm-1.0-r3/work/qemu-kvm-1.0/memory.c:1239: memory_region_add_subregion_common: Assertion `!subregion->parent' failed. I searched for that assertion and found this thread, but it looks only slightly relevant, and didn't have any thoughts for a fix http://comments.gmane.org/gmane.comp.emulators.kvm.devel/80653 Downgrading back to 0.15.1-r1 (vgabios package auto removed) works normally. It looks like a possible bug, but I may be doing something wrong. Does this work for anybody? Reproducible: Always Steps to Reproduce: install qemu-kvm-v0.15.1-r1 create a vm using the vga bios type try to start the vm Actual Results: vm terminates instantly, logging that assertion failure Expected Results: vm should start normally

Can you attach the command line generated to execute this VM?
Created attachment 306585 [details] Attached command line for one of the VMs that will not boot Command is attached. Thanks
If you stop your VM, edit it with "virsh edit VMNAME" and change it from pc-0.13 to pc-0.14, does the problem go away with qemu-kvm-1.0? My bet is that it will.
Thank you Doug, that did the trick just fine. Interestingly enough, I did have a couple VMs created more recently that were not set to auto start and I don't use. Editing these showed they were already at 0.14 and working fine the whole time. So it appears this bug only affects VMs created _____ months ago on an older version where the machine version got set to 0.13 instead of 0.14. Do you know what the story is here? It is probably just a missing note in the emerge output, vs all the trouble of making a code change to keep supporting <=0.13 ...
Just an issue with the old way Qemu added VBE memory regions into the VM. Newer versions of vgabios support actually reporting what they use and act as a realer (to invent a word) Video BIOS than past versions. This resulted in the hardcoded way the Qemu used to use conflicting with what the Video BIOS reported. By saying you wanted Qemu machine type from 0.13 you enabled the hardcoded hack, but Qemu still attempted to respect what the Video BIOS said. So conflict. By using Qemu machine type 0.14 or newer, the hardcoded hack is gone and it relies on the Video BIOS to do the right thing. The unfortunate thing is that there's no way to setup depends to prevent this from happening. Its more or less an individual config thing.
Yep, definitively works for me. Thank you for jumping on this so quickly. However, at the very minimum I think it warrants a small note when upgrading. " <type arch='*' machine='pc-0.13'>*</type> 0.13 or older is no longer supported as of 0.15.1-r1, you must manually upgrade your vm definition to use <type arch='*' machine='pc-0.14'>*</type> due to [what you just said]." Otherwise the poor user out there is stuck and may not be lucky enough to stumble into this bug report. Depending on if it's widespread enough or not ... if myself and the other CC are the only two affected, don't bother; however I would think there will be more to come soon. Thanks again Doug!
