Some time ago I cloned a disk image of an old Solaris legacy system and was able to successfully boot and use it within QEMU. Recently I upgraded my host from i386 Ubuntu 12.04 to a new box running x86_64 Ubuntu 12.10. Now I find that the same qemu command line results in that guest failing to boot with a "no active boot partition" error message.
The command I have been using is:
qemu-system-i386 \
-machine pc,accel=kvm \
-m 256M \
-vga std \
-net nic,vlan=1,model=pcnet \
-net user,vlan=1,hostfwd=::8050-$GUEST:22 \
-hda "$DISK"
I find that if I change to "accel=tcg" in above command (or add -no-kvm) then the guest will boot ok but I find my host works much harder & slower than when I use kvm. Is there a qemu option so I can use kvm but get around this guest boot issue?
Thanks,
