Hi, first of all, my name is Karsten and I am fairly new to xen. A former colleague of mine has set up a xen dom0 with 4 virtual machines runnig on it. A few months ago this colleague left the company. Last week our office Building has been hit by a lightning wich resulted in an power blackout. After the power went back again, the system booted and all but one of the virtual machines went back. The virtual machine that did not went back seems not to be able to boot, i see some kind of grub error. The console of this machine prints out: ===== Plex86/Bochs VGABios current-cvs 07 Jun 2008 This VGA/VBE Bios is released under the GNU LGPL Please visit : * http://bochs.soureeferge.net * http://www.nongnu.org/vgabios cirrus-compatible VGA is detected HVMAssist BIOS, 1 Cpu, $Revision: 1.138 $ $Date: 2005/05/07 15:55:26 $ ata0 master: QEMU HARDDISK ATA-7 Hard-Disk (35840 MBgtes) ata0 slave: Unknown device ata1 master: masteri QEMU CD-ROM ATAPI-4 CD-Rom/DVD-Rom ata1 slave: Unknown device Booting from Hard Disk... GRUB GRUB _ ===== After this, the boot process hangs and the vm seems to be verry busy, CPU goes up to 100%. The host system seems to be OpenSuSE 11.0, while the virtual machine is running debian 4.0. The configuration of this virtual machine: ==== erde:/ # cat /etc/xen/vm/VM4 name="VM4" uuid="67896e91-b77f-edcc-48c8-ef3016821ecd" memory=512 vcpus=2 on_poweroff="destroy" on_reboot="restart" on_crash="destroy" localtime=0 builder="hvm" extid=0 device_model="/usr/lib/xen/bin/qemu-dm" kernel="/usr/lib/xen/boot/hvmloader" boot="c" disk=[ 'file:/var/lib/xen/images/VM4/disk0,hda,w', 'phy:/dev/cdrom,hdc:cdrom,r', ] vif=[ 'mac=00:16:3e:62:62:80,model=rtl8139,type=ioemu', ] stdvga=0 vnc=1 vncunused=1 apic=0 acpi=1 pae=1 serial="pty" ==== I tried to attach the DomU disk image of this machine to Dom0 using xm bock-attach and it worked. All files are there, e2fsck did not find any errors. So my question is, how can i recover this virtual machine? I there a chance to re-install grub? What is the meaning of this "GRUB GRUB" printed out by grub?
