I am using pygrub to boot and this is how I got it to work: xm create -c <path to >dev3.cfg at the boot splash select the kernel you are using to boot with.. press e to edit. press e and edit the kernel line and put single right after the kernel designation.... i.e. kernel /vmlinuz-2.6.18-274.3.1.el5xen single ro root=/dev/VolGroup00/LogVol00 ..... press enter to save your change. It will return back to the boot option menu pyGRUB version 0.6 ┌────────────────────────────────────────────────────────────────────────┐ │ kernel /vmlinuz-2.6.18-274.3.1.el5xen single ro root=/dev/VolGroup00/> │ │ initrd /initrd-2.6.18-274.3.1.el5xen.img │ │ │ │ │ │ │ │ │ │ │ │ │ └────────────────────────────────────────────────────────────────────────┘ Use the ^ and v keys to select which entry is highlighted. Press 'b' to boot, 'e' to edit the selected command in the boot sequence, 'c' for a command-line, 'o' to open a new line after ('O' for before) the selected line, 'd' to remove the selected line, or escape to go back to the main menu. hit b to boot... it worked for me a couple of times in succession. Good luck. You could loop mount the messed up disk on the host or you could mount the messed up disk on another DomU and change it.

Does anyone know how to do that? I tried adding single to the extras line in /etc/xen/machine_name but it still tries to start in level 3. To make things worse, the root partition is on LVM. Alternatively, does anyone know how to access the image from DomU? I tried to use kpartx but when I run VGscan, I do not get the lvm activated.
