similar to: Bind mounts

Hi, I asked the question on stackexchange (http://unix.stackexchange.com/questions/264931/centos-7-unable-to-cleanly-umount-a-bind-mount-using-rbind-and-rslave) and CentOS 7 bug report (https://bugs.centos.org/view.php?id=10414) but didn't get any useful response, so I am thinking if I can get some help here. The problem arose when I tried to rbind mount /dev and /proc to a chroot sandbox

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

Simply a file rename, no other change. --- daemon/Makefile.am | 2 +- daemon/command.c | 319 ----------------------------------------------------- daemon/sh.c | 319 +++++++++++++++++++++++++++++++++++++++++++++++++++++ po/POTFILES | 2 +- 4 files changed, 321 insertions(+), 321 deletions(-) delete mode 100644 daemon/command.c create mode 100644 daemon/sh.c diff --git

Hi all, Sorry for bothering you in this dev mailing list, I'm using libguestfs to customize some vm using as bases the ubuntu cloud images. But I noticed that it takes a lot and then fails when trying to install a packet. Same behaviour on Ubuntu 18.04 and Centos 7.5 Ubuntu: virt-customize 1.36.13 libvirtd (libvirt) 4.0.0 Centos: virt-customize 1.36.10rhel=7,release=6.el7_5.2,libvirt

When possible, make the disk image format explicit when invoking tools or using add-drive. This avoids warnings from qemu about the unspecified format for the image, and also makes qemu slightly faster (skipping the disk image probing). Tests checking the image probing are not touched. This changes also: - old-style invocations of tools (`$tool $filename`) into new style (`$tool -a $filename`)

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

hi Jones, Sorry for the late reply. when I used your method to execute command: $guestfish -N fs:xfs -m /dev/sda1 statvfs / libguestfs: error: mkfs: xfs: /dev/sda1: mkfs.xfs: No such file or directory guestfish: error creating prepared disk image 'fs:xfs' on 'test1.img': failed to create filesystem (xfs): mkfs: xfs: /dev/sda1: mkfs.xfs: No such file or directory does I need to

Sadly, there are elements (hello "gentoo"!) that, during the cleanup.d phase, wipe out almost everything in the /tmp of the guest, including the /tmp/aux where virt-dib mounts the auxiliary data. Since that removal excludes things starting with "in_target" (mostly to avoid wiping the "in_target.d" that disk-image-create itself sets up, then rename our "aux"

With 1.9.37 the following script worked fine, with 1.9.39 it fails. Any idea what the issue is?

virt-dib is a new tool to run the elements of diskimage-builder using libguestfs. --- Work in progress (debug stuff here and there), although I've submitting it for initial review, for being included later when polished for good.
