v1 was here: https://www.redhat.com/archives/libguestfs/2016-March/thread.html#00157 Not running the 'hwclock' command reduces boot times considerably. However I'm not sure if it is safe. See the question I posted on qemu-devel: http://thread.gmane.org/gmane.comp.emulators.qemu/402194 At the moment, about 50% of the time is consumed by SeaBIOS. Of this, about ⅓rd is SGABIOS

v4: - Lots more analysis of the /init script and other parts. - Display a list of the longest to shortest activities. - Rebase on top of current head. Rich.

This patch reworks how we start up LVM and lvmetad. It fixes the problem we had converting a guest which had a peculiar LVM configuration: https://bugzilla.redhat.com/show_bug.cgi?id=1581810#c14 However please note I have NOT yet tested it fully. Rich.

Lots of changes since v2, too much to remember or summarize. Please ignore patch 11/11, it's just for my testing. Rich.

This set of patches fixes virt-rescue rather cleanly. In particular the problems with handling ^C are completely fixed. Work still to be done before this can go upstream: - Shutdown doesn't work properly if you exit the shell. At the moment to exit you must do 'reboot -f'. Future improvements: - An escape sequence and escape commands that could be handled by virt-rescue,

This fixes the main issues in virt-rescue and is usable. There are some enhancements which could be made (in follow up work): - An escape sequence and escape commands that could be handled by virt-rescue, eg. to shut down the appliance, mount or unmount filesystems. - `virt-rescue -i' could be implemented cleanly by performing the right API calls before handing control to the

This supersedes the two previous patch series: https://www.redhat.com/archives/libguestfs/2017-March/msg00017.html https://www.redhat.com/archives/libguestfs/2017-March/msg00046.html Rich.

Hi, I have a KVM host running ubuntu 18.04 with libguestfs-tools version 1.36.13-1ubuntu3.3 installed from the Ubuntu's repo and when I try to use virt-cat for example on a VM it fails with: libguestfs: error: appliance closed the connection unexpectedly. > libguestfs: error: guestfs_launch failed.
