Re: Hugepages -- "Memory backend 'pc.ram' not found"

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.
