Hi, I want to migrate from vmware to KVM. Therefore I have installed debian stable (lenny) and create two virtual machines (KVM). Both (XP as well as Vista) running fine. After upgrading to debian testing (sqeeze) both XP-guest as well as Vista-guest didn't start anymore. Both are failing during preparation, probably because of a network-problem. I will give XP as an example: cat /var/log/libvirt/qemu/devel-xp.log.2 /usr/bin/kvm -S -M pc -m 256 -smp 1 -name devel-xp -monitor pty -localtime -no-acpi -boot c -drive file=/KVM-Images/devel-xp.qcow2,if=ide,index=0,boot=on -drive file=/mnt/MultiMedia/CD-Server/Betriebssysteme/Windows/WindowsNT/WindowsXPpro_sp2_de.iso,if=ide,media=cdrom,index=2 -net nic,macaddr=54:52:00:29:1a:2d,vlan=0 -net tap,fd=11,script=,vlan=0,ifname=vnet0 -serial pty -parallel none -usb -usbdevice tablet -vnc 127.0.0.1:0 -k de char device redirected to /dev/pts/1 char device redirected to /dev/pts/2 info cpus -> the above will run fine before the upgrade the following will fail after the upgrade tail /var/log/messages: Jan 8 00:56:33 linux-dev libvirtd: 00:56:33.461: warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit status '1', qemu probably failed Jan 8 00:56:33 linux-dev kernel: [ 1903.710664] device vnet0 entered promiscuous mode Jan 8 00:56:33 linux-dev kernel: [ 1903.711011] br0: port 2(vnet0) entering learning state Jan 8 00:56:33 linux-dev kernel: [ 1904.022502] br0: port 2(vnet0) entering disabled state Jan 8 00:56:33 linux-dev kernel: [ 1904.024752] device vnet0 left promiscuous mode Jan 8 00:56:33 linux-dev kernel: [ 1904.024752] br0: port 2(vnet0) entering disabled state tail -f /var/log/libvirt/qemu/devel-xp.log LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin HOME=/ QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name devel-xp -uuid 1b412c63-dcc0-739f-3c27-630147e6b162 -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/devel-xp.monitor,server,nowait -mon chardev=monitor,mode=readline -rtc base=localtime -no-acpi -boot c -drive file=/KVM-Images/devel-xp.qcow2,if=none,id=drive-ide0-0-0,boot=on,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive file=/mnt/MultiMedia/CD-Server/Betriebssysteme/Windows/WindowsNT/WindowsXPpro_sp2_de.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 -device rtl8139,vlan=0,id=net0,mac=54:52:00:29:1a:2d,bus=pci.0,addr=0x3 -net tap,fd=40,vlan=0,name=hostnet0 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -device usb-tablet,id=input0 -vnc 127.0.0.1:0 -k de -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 char device redirected to /dev/pts/4 TUNGETIFF ioctl() failed: Invalid argument exception 13 (0) rax 0000000000000010 rbx 0000000000008c00 rcx 0000000000006eb6 rdx 00000000000c8c00 rsi 00000000f2010000 rdi 00000000000c0000 rsp 0000000000006eac rbp 00000000f2010000 r8 0000000000000000 r9 0000000000000000 r10 0000000000000000 r11 0000000000000000 r12 0000000000000000 r13 0000000000000000 r14 0000000000000000 r15 0000000000000000 rip 00000000000fde7c rflags 00033002 cs 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ds 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) es 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) ss 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) fs 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) gs 0000 (00000000/0000ffff p 1 dpl 3 db 0 s 1 type 3 l 0 g 0 avl 0) tr 0000 (feffd000/00002088 p 1 dpl 0 db 0 s 0 type b l 0 g 0 avl 0) ldt 0000 (00000000/0000ffff p 1 dpl 0 db 0 s 0 type 2 l 0 g 0 avl 0) gdt f7910/37 idt f8990/0 cr0 10 cr2 0 cr3 0 cr4 0 cr8 0 efer 0 code: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 --> 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Any hints?
