opensuse 11.4 xenserver hang boot reboot guest

  • Ok great! I think I have a solution. For me this reduces the bug from 1 in 5 times, to around 1 in 1000. I still see the bug but this helps a bunch: ======== My Almost 100% Solution!! ======== Edit /etc/inittab. Comment out all of the normal tty's (they are unused in PV mode). For example: Code: #1:2345:respawn:/sbin/mingetty --noclear tty1 #2:2345:respawn:/sbin/mingetty tty2 #3:2345:respawn:/sbin/mingetty tty3 #4:2345:respawn:/sbin/mingetty tty4 #5:2345:respawn:/sbin/mingetty tty5 #6:2345:respawn:/sbin/mingetty tty6 Near the end of the file, there (may) should be a cons entry. Comment it out as well Code: #cons:12345:respawn:/sbin/smart_agetty -L 42 console add this line to the end of inittab: Code: co:2345:respawn:/sbin/agetty xvc0 9600 vt102 From XenCenter: Right click on the VM, click Startup Options. Replace all the text in OS Boot Parameters with this: Code: xencons=xvc console=xvc0

  • Create a VM from the Other install media template
  • Attach the Ubuntu 10.04 ISO to the DVD drive of the VM
  • Start the VM
  • ...19 more annotations...
  • At the disk partitioning stage make sure to replace Ext4 with Ext3, or create a specific boot partition with Ext3
  • Select at least the OpenSSH server package to be able to log in to the VM remotely
  • Finish installation and boot the VM
  • Connect to the VM using SSH
  • sudo cp /etc/init/tty1.conf /etc/init/hvc0.conf sudo vi /etc/init/hvc0.conf
  • Replace all occurrences of tty1 with hvc0
  • Read /boot/grub/grub.cfg
  • Copy the contents of menuentry near the bottom to a temporary text file, to be used as input for the makepv.sh script that we will use later on menuentry 'Ubuntu, with Linux 2.6.32-21-server' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 02899ea9-1876-4e7b-8ef8-2b09b598cedb linux /boot/vmlinuz-2.6.32-21-server root=UUID=02899ea9-1876-4e7b-8ef8-2b09b598cedb ro quiet initrd /boot/initrd.img-2.6.32-21-server }
  • Make special note of /boot/vmlinuz…, root=UUID=… and /boot/initrd.img…
  • Shutdown the VM
  • Connect to the XenServer host with SSH
  • Run the makepv.sh script, replacing my-vm-name with the actual name of your VM
  • Boot the VM and log in with SSH
  • In XenCenter, attach xs-tools.iso to the DVD drive of the VM
  • sudo mount /dev/cdrom1 /mnt sudo dpkg -i /mnt/Linux/xe-guest-utilities_5.5.0-466_amd64.deb sudo umount /mnt
  • In XenCenter, detach xs-tools.iso from the DVD drive of the VM (this ensures that XenServer does not complain about too many bootable devices)
  • Reboot the VM and log in with SSH
  • sudo update-rc.d -f xe-linux-distribution remove sudo update-rc.d xe-linux-distribution defaults
  • Reboot the VM for the last time
