I routinely test-drive sculpt in Qemu running in my Linux VM on top of
Sculpt using the gems/run/sculpt_test.run script. So Sculpt should in
principle come up in KVM on a native Linux system.

For reference, in my test scenario the Qemu command line looks as follows:

qemu-system-x86_64 \
  -no-kvm \
  -display sdl \
  -cpu core2duo \
  -m 768 -net nic,model=e1000 -net user \
  -serial mon:stdio \
  -device ahci,id=ahci \
  -drive id=hdd,file=bin/sculpt-ahci.raw,format=raw,if=none \
  -device ide-hd,drive=hdd,bus=ahci.1 \
  -drive format=raw,file=var/run/sculpt.img \
  -machine q35

I agree. In Qemu without KVM, it is bearable for testing but not for using.

Regarding nested virtualization in Qemu/KVM, you'd need to enable at
least the AMD Phenom CPU model (-cpu phenom) in Qemu. Our automated
tests of the Seoul VMM (as used in Sculpt's 'seoul-vmm-browser package')
work that way. But I have not used this configuration interactively.

Cheers
Norman
