OK. So kqemu was dropped, that's fine. But what about systems that don't
have VT-enabled hardware but would still like to use vmbuilder?
In 8.04 it was possible to use 'ubuntu-vm-builder qemu hardy', but now
only (forgetting about vmware and xen for a moment) 'vmbuilder kvm
hardy' works. Without kvm module initialized, this operation fails. I'd
like to have virtualized systems inside of already virtualized system
(therefor, no hardware acceleration). Errors:
libvir: Domain Config error : internal error no supported architecture
for os type 'hvm'
libvirt.libvirtError: internal error no supported architecture for os
Basically, vmbuilder does the whole work, but dies on XML generation (if
you use --debug, you actually get to see generated xml). And if XML is
created by hand, libvirt starts it with command:
QEMU_AUDIO_DRV=none /usr/bin/qemu -S -M pc-0.12 -no-kvm -m 512 -smp 1
-name test -uuid 7d78cbee-3832-ca61-ffdb-d3ec63c8db19 -chardev
-monitor chardev:monitor -no-acpi -boot c -drive
none -serial none -parallel none -usb -vnc 192.168.79.2:0 -vga cirrus
And this fails (system never loads grub completely). But if 'boot=on'
(in drive setup) is removed or replaced with 'boot=off' and then started
by hand, everything works fine.
Is all of this on purpose or is it a bug (or bugs)?
