Hello,
After defining hugepages, as documented at https://libvirt.org/formatdomain.html#memory-backing , when I start the guest, I get a dialogue box that says:
Error starting domain: internal error: qemu unexpectedly closed the monitor: 2022-02-20T01:10:36.520955Z qemu-system-x86_64: Memory backend 'pc.ram' not found Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 65, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 101, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/object/libvirtobject.py", line 57, in newfn ret = fn(self, *args, **kwargs) File "/usr/share/virt-manager/virtManager/object/domain.py", line 1329, in startup self._backend.create() File "/usr/lib64/python3.9/site-packages/libvirt.py", line 1353, in create raise libvirtError('virDomainCreate() failed'
After backing out changes, guest starts normally. I searched online for the error message, but found nothing useful. The hypervisor is running libvirtd (libvirt) 7.8.0 and QEMU emulator version 6.1.0, both build from source. I've got plenty of hugepages available. The domain's XML definition is attached.
Hey, can you share your domain XML and the generated cmd line? The latter should be found in /var/log/libvirt/qemu/$domain.log Thanks, Michal
