Hello, I have a KVM virtualization problem. I've put together new hardware (supermicro) server with 2 E5530 cpu's and memory & disk to start experimenting with virtualization. I intend to use the www.proxmox.com system/setup. I installed proxmox and started stress testing the hardware: parallel kernel compiles in a loop (concurrency_level=32) & memtest86+ during the night etc. The hardware/os performs rocksolid when i stress test it, but the moment i start a virtual guest (eg debian netinstall) i get the first screen of the installation procedure in a vnc screen. I choose either normal install or expert install , the guest screen goes blank with only a cursor and the kvm process prints an error on the console and starts to eat cpu cycles. So the host OS is not barfing, only the kvm process is giving problems and the guest is frozen. To see if it was/is related to the "older" proxmox kernel setup i installed ubuntu karmic with libvirt on another harddrive for comparison: Same error happens when i start a guest.

I spoke to supermicro support and even got a more recent (yet unpublished) bios. All without success. No i am up to the point where i dont know if i have a hardware or a software problem. I installed the intel-microcode package to see if that maybe fixed something: It didn't References: chassis: http://supermicro.com/products/system/2U/6026/SYS-6026TT-BIBQRF.cfm?INF= motherboard: http://supermicro.com/products/motherboard/QPI/5500/X8DTT-F.cfm 7 hourmemtest: http://dth.net/supermicro/memtest86_completed_7hr.jpg More output (dmesg and other stuff) in the same dir: http://dth.net/supermicro/ Am i trying to run this on hardware that is to recent and not yet tested ? I hope somebody has some ideas/hints about this.
