* PATCH FOR DISCUSSION ONLY - NOT TO BE APPLIED * Colin suggested something which seems eminently sensible: https://bugzilla.redhat.com/show_bug.cgi?id=916780 I've been through a couple of rounds of trying to implement this. I started with adding the option as suggested to the guestmount program, but it tended to make the guestmount program more complex. More importantly, adding the option

The full description of this bug is here: https://bugzilla.redhat.com/show_bug.cgi?id=838592 and the effect it has on OpenStack is described here: https://bugzilla.redhat.com/show_bug.cgi?id=835466#c9 Rich.

Since the first patch: - The program is now called 'guestunmount'. - I tested the --fd option and it appears to work. - You can now control retries / quiet. - Revised man pages. - Includes tests. I'm just running through the automated tests now. Rich.

Hello everyone! I'm playing with guestunmount and got the following issues: 1) guestunmount never returns 3 (not mounted) - i guess it's a bug at guestunmount.c:223 2) I don't know whether it's a bug in guestunmount or fusermount, but on my machine while executing > guestmount > guestunmount > guestunmount on second "guestunmount" I get

This version doesn't crash or cause hung processes or stuck mountpoints, so that's an improvement. Rich.

How can i open a virtual disk in read-write mode ? # guestmount --rw -d winxp -m /dev/sda1 /media/ # rm -f /media/pagefile.sys rm: cannot remove ?/media/pagefile.sys?: Operation not permitted # cd /media && touch file touch: cannot touch ?file?: Permission denied # cd && fusermount -u /media I've tried with guestfish also. I have compiled libguestfs with this conf:

This changes the proposed API slightly. Previously 'mount-local' generating a 'mounted' event when the filesystem was ready, and from the 'mounted' event you had to effectively do a fork. Now, 'mount-local' just initializes the mountpoint and you have to call 'mount-local-run' to enter the FUSE main loop. Between these calls you can do a fork or whatever

Hello, I have a vmdk having an LV with an ext3 FS where some files have extended attributes and acls set. These do not appear set while accessing them when mounted using guestmount. I do not know if it is easy or difficult to implement this, so I'd like to take your opinion. what I did was changed the default mount options in daemon/mount.c from "ro" to

Hi, I'm experiencing a weird behavior when tried to use guestmount with a XFS formatted volume. I have created a RHEL 8 virtual machine using libvirt. I have retrieved the disk image on a RHEL 7.7 server to mount the image root filesystem and explore it. The command returns an error message: # guestmount -a /disks/jamesdream.qcow2 -m /dev/sda1 /mnt/ libguestfs: error: mount_options: mount

Hello, I've got a strange behavior with guestmount: I've a root directory with mod/owner = drwx------ root root. I cannot change directory to it as a regular user (as normal), but I can list its content (not normally normal) and I can change directory to a subdirectory in it which is mod drwxr-xr-x. E.g: $ mkdir /tmp/mnt $ guestmount --ro -i -a test.qcow2 /tmp/mnt/ $ cd /tmp/mnt $ ls -ld

Hi, Apparently, guestmount -o allow_other -a "/path/to/raw_file" -m /dev/sda1 "/path/to/mountfolder" is much slower than kpartx -av "/path/to/raw_file" mount /dev/mapper/loop0p1 /path/to/mountfolder (Doing lots of read/write inside the image.) I thought guestmount "only" scripts the above. Seems I was wrong on that. I am currently using

This patch is just for review. It enables FUSE support in the API via two new calls, 'guestfs_mount_local' and 'guestfs_umount_local'. FUSE turns out to be very easy to deadlock (necessitating that the machine be rebooted). Running the test from the third patch is usually an effective way to demonstrate this. However I have not yet managed to produce a simple reproducer that
