Xen on Qemu on Xen
The Emulation vs Virtualization seminar has been a success, we had 20 persons listening on site and the average network listener number has been said to be 60.
At the end of the seminar, we tried some bad ass crazy thing: to run a XenLinux inside Qemu, while Qemu is running on XenLinux. It worked.
The machine had a Vanderpool supporting cpu, and we used the domain0 for running Qemu in it. Qemu has been started in snapshot mode and the boot disk has been the raw device it was running on already. So the same system booted in Qemu. A domain1 Linux has been started successfully, sadly we hadnt much time then, so we failed to start up X perfectly – the VESA driver produced bad color patterns.
Anyway, it was a great success.
You can listen to it at the NIIF video on demand archive (but only in Hungarian).
