Can you check the dmesg logs.

It will reflect issues if BIOS virtualization is disabled.

I still feel the BIOS settings got changed to have virtualization disabled.

A search trough the web suggest that kernel modules are not loaded.  I
my case, they are:

# lsmod | fgrep kvm

kvm                   451511  1 kvm_intel
Let me take a wild guess: your <servername>.xml file specifies the use
of kvm in an oldway which is no longer supported by your new versions
of libvirt and qemu.

The phrase "hvm" (if that is how it is spelled in the XML) may refer
to a XEN hvm setup, not a Linux kvm setup.
