[Qemu-discuss] KVM nested virtualization

[siddhesh phadke]

I am a newbie in nested virtualization.

I am trying to install ubuntu 10.04 inside normal guest (ubuntu 10.04) but vnc screen hangs after showing intial install screen. If i copy working disk image inside normal guest using scp and then run it as nested guest still vnc screen hangs as in nothing happens on screen. 

Can any one of you help me with this?

host machine:
 Quad-Core AMD Opteron(tm) Processor 2376

I ran following on host machine,

sudo qemu-system-x86_64 -hda vdisk.img -m 4096 -cpu qemu64,+svm -smp 4 -net nic,macaddr=52:54:00:xx:xx:xx  -net tap,ifname=qtap5,script=no,downscript=no -vnc :2  -usbdevice tablet

I ran following on guest machine,

qemu-system-x86_64 -hda guest.img -cdrom ubuntu-10.04.4-desktop-amd64.iso -boot d -m 2048 -vnc :2
