virt-rescue [--options] -a disk.img [-a disk.img ...]
+ virt-rescue --suggest (-d domname | -a disk.img ...)
+
Old style:
virt-rescue [--options] domname
hand. There is an empty directory called C</sysroot> where you can
mount filesystems.
-In the example below, we list logical volumes, then choose one to
-mount under C</sysroot>:
+You can get virt-rescue to suggest mount commands for you by using the
+I<--suggest> option (in another terminal):
+
+ $ virt-rescue --suggest -d Fedora15
+ Inspecting the virtual machine or disk image ...
+
+ This disk contains one or more operating systems. You can use these
+ mount commands in virt-rescue (at the ><rescue> prompt) to mount the
+ filesystems.
+
+ # /dev/vg_f15x32/lv_root is the root of a linux operating system
+ # type: linux, distro: fedora, version: 15.0
+ # Fedora release 15 (Lovelock)
+
+ mount /dev/vg_f15x32/lv_root /sysroot/
+ mount /dev/vda1 /sysroot/boot
+ mount --bind /dev /sysroot/dev
+ mount --bind /dev/pts /sysroot/dev/pts
+ mount --bind /proc /sysroot/proc
+ mount --bind /sys /sysroot/sys
+
+Another way is to list the logical volumes (with L<lvs(8)>) and
+partitions (with L<parted(8)>) and mount them by hand:
><rescue> lvs
LV VG Attr LSize Origin Snap% Move Log Copy% Convert
- lv_root vg_f11x64 -wi-a- 8.83G
- lv_swap vg_f11x64 -wi-a- 992.00M
- ><rescue> mount /dev/vg_f11x64/lv_root /sysroot
+ lv_root vg_f15x32 -wi-a- 8.83G
+ lv_swap vg_f15x32 -wi-a- 992.00M
+ ><rescue> mount /dev/vg_f15x32/lv_root /sysroot
+ ><rescue> mount /dev/vda1 /sysroot/boot
><rescue> ls /sysroot
-If you don't know what filesystems are available on the virtual
-machine then you can use commands such as L<parted(8)> and L<lvs(8)>
-to find out.
+Another command to list available filesystems is
+L<virt-filesystems(1)>.
+
+To run commands in a Linux guest (for example, grub), you should
+chroot into the /sysroot directory first:
+
+ ><rescue> chroot /sysroot
