Re: Nested Virtualization Of Hyper-V 2K8R2

[Jim <jim@suresafe.co.uk>]

Hi Joerg,

Sure, the KVM command is :

/usr/bin/kvm -enable-nesting -no-kvm-irqchip -S -M pc-0.14 -enable-kvm 
-m 2048 -smp 2,sockets=2,cores=1,threads=1 -name hyperv1 -uuid 
8c5d8f1f-5767-b388-d408-1b53a1b66e72 -nodefconfig -nodefaults -chardev 
socket,id=charmonitor,path=/var/lib/libvirt/qemu/hyperv1.monitor,server,nowait 
-mon chardev=charmonitor,id=monitor,mode=readline -rtc base=localtime 
-no-reboot -boot d -drive 
file=/srv/hyperv/hyperv1.vmimg,if=none,id=drive-ide0-0-0,format=raw 
-device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 
-drive 
file=/srv/virtual-machines/fromiscsi/iso/W2K8ENTR2SP1.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw 
-device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 
-drive 
file=/srv/virtual-machines/fromiscsi/iso/virtio-win-1.1.16.iso,if=none,media=cdrom,id=drive-ide0-1-1,readonly=on,format=raw 
-device ide-drive,bus=ide.1,unit=1,drive=drive-ide0-1-1,id=ide0-1-1 
-netdev tap,fd=17,id=hostnet0 -device 
rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:2a:be:2f,bus=pci.0,addr=0x3 
-chardev pty,id=charserial0 -device 
isa-serial,chardev=charserial0,id=serial0 -usb -device 
usb-tablet,id=input0 -vnc 127.0.0.1:0 -vga std -device 
virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4

This is started via virsh.
