Hello,
According to WikiPedia VIA claims x86 hardware assisted virtualization
for VIA Eden X4 CPU.
Does anybody know if it is supported by Linux KVM?

I can't say for sure but my guess is that it should work since VIA implements
VT-x like virtualization extensions, so KVM will find VMX capable hardware.

Do I understand correctly, that VIA engineers are not frequent guests
here and VIA doesn't disclosure docs for their CPUs?

I don't think it's that straightforward, ISTR the vmx capability on
previous VIA processors being broken, for instance:
https://bugs.launchpad.net/qemu/+bug/712416
Seems like Avi had investigated and found something pretty broken in
the implementation, but my google-foo isn't able to find the thread. I
suspect nobody, maybe not even VIA, knows if it works on their latest
attempt. Thanks,
Alex
