similar to: [PATCH 0/2] Add a 'virt-rescue' command

This is continuing/summarising a rather long discussion that happened on IRC ... We talked to some SELinux experts about what was required to make SELinux work with libguestfs, and it seems reasonably simple to load the policy from the guest filesystem. All that needs to be done is to mount the guest disks up and then run: sh "/usr/sbin/load_policy -i" That command also mounts up

These commands let you set and get the SELinux context of the daemon and all operations in the API and processes run from the daemon: $ ./fish/guestfish --ro -a /dev/mapper/vg_trick-F11x64 \ selinux 1 : \ run : \ mount /dev/vg_f11x64/lv_root / : \ sh "/usr/sbin/load_policy" : \ getcon : \ setcon "system_u:system_r:unconfined_t:s0" : \ getcon

With kernel 2.6.30-rc2-git6 and prior I am having problems mounting ext4 partitions after reboot. A successful mount looks like this: /dev/cciss/c0d0p8 on /squid-cache0 type ext4 (rw,noexec,nodev,noatime,data=writeback,errors=panic) /dev/cciss/c0d0p9 on /squid-cache1 type ext4 (rw,noexec,nodev,noatime,data=writeback,errors=panic) /dev/cciss/c0d0p10 on /squid-data type ext4

Since /dev and other directories contain sub-mounts, suggest using --rbind instead of --bind. This also allows us to remove the /dev/pts line. --- rescue/rescue.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/rescue/rescue.c b/rescue/rescue.c index 53afdae..9a7c988 100644 --- a/rescue/rescue.c +++ b/rescue/rescue.c @@ -453,10 +453,9 @@ do_suggestion (struct drv

At the moment the daemon code contains an incredibly hairy function called shell_quote for safely quoting strings passed to the shell. The patch replaces that with a glibc custom printf format (actually two, but very closely related), %Q and %R. %Q is like %s but it safely shell quotes the string. %R is like %Q but it prefixes the path with /sysroot. Example usage (w/o error checks):

Hello, I am trying to run this command virt-rescue --suggest -d XYZ virt-rescue --network -d XYZ the prompt is looking like this: I have no name!@(none): now I mounted the root partition suggested by virt-rescue to /sysroot then chroot /sysroot after that I tried to rebuild an initrd.img with the following command update-initramfs -c -k 3.2.0-58-generic But it failed with following error:

I'm having an occasional problem with a box. It's a Supermicro 16-core Xeon, running CentOS 6.3 with kernel 2.6.32-279.el6.x86_64, 96 gigs of RAM, and an Areca 1882ix-24 RAID controller with 24 disks, 23 in RAID6 plus a hot spare. The RAID is divided into 3 partitions, two of 25 TB plus one for the rest. Lately, I've noticed sporadic hangs on writing to the RAID, which

Hello all, I've got heavy troubles with my ocfs2 environment. Cluster filesystem worked fine for about 3-6 weeks after initial setup, but since 1 week performance issues occurs. I've already searched long time in google and on this mailing list but I wasn't able to found any solution. I've found a lot of posts with "same" problems but without the magic answer :-)
