It detects host as Penryn as well for @tstrike. Which is fine if it is a chip of around that era. He reported to have an "Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz" And for that chip the detection and chip used might be correct.
So to summarize all repro fails, but on Penryn ERA chips 2/2 cases trigger the bug. I wonder if one that wants to reproduce needs a system with such a chip as well then to test and trigger this. There should be plenty of people on CC as this is mirrored to qemu-devel due to the upstream qemu task. Is there an microarchitectural x86 specialist that knows if the chips of that generation have some special issues in regard to VMX that might explain what we see here? It would be great if everyone could ask around for more systems with chips of that era. Maybe we can further bisect which work and which will fail. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 Status in QEMU: New Status in qemu package in Ubuntu: Incomplete Bug description: Symptom: Error unpausing domain: internal error: unable to execute QEMU command 'cont': Resetting the Virtual Machine is required Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 75, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 111, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/object/libvirtobject.py", line 66, in newfn ret = fn(self, *args, **kwargs) File "/usr/share/virt-manager/virtManager/object/domain.py", line 1311, in resume self._backend.resume() File "/usr/lib/python3/dist-packages/libvirt.py", line 2174, in resume if ret == -1: raise libvirtError ('virDomainResume() failed', dom=self) libvirt.libvirtError: internal error: unable to execute QEMU command 'cont': Resetting the Virtual Machine is required --- As outlined here: https://bugs.launchpad.net/qemu/+bug/1813165/comments/15 After upgrade, all KVM guests are in a default pause state. Even after forcing them off via virsh, and restarting them the guests are paused. These Guests are not nested. A lot of diganostic information are outlined in the previous bug report link provided. The solution mentioned in previous report had been allegedly integrated into the downstream updates.
