Description Richard W.M. Jones 2017-04-04 05:07:31 EDT
Description of problem:

The new virt-rescue is much better than the old version.  In particular,
major bugs like ^C killing the whole program are fixed.  Also supports
`-i' to mount all the disks and an escape key.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Run: virt-rescue --scratch

Actual results:

Try using ^C - it will kill the whole program.

Expected results:

^C, ^Z should work as expected.

There is an escape key: try using ^] h

You can also do:

  $ virt-builder fedora-25
  $ virt-rescue -a fedora-25.img -i

and it should automatically mount the guest's disks under /sysroot
inside the rescue shell.

Comment 4 YongkuiGuo 2017-11-16 04:03:18 EST
Verified with package:


1. #virt-rescue --scratch
The virt-rescue escape key is ‘^]’.  Type ‘^] h’ for help.

Welcome to virt-rescue, the libguestfs rescue shell.

Note: The contents of / (root) are the rescue appliance.
You have to mount the guest's partitions under /sysroot
before you can examine them.

bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
><rescue> ^]q

2. ^C and ^Z don't kill the rescue shell.

3. ^]q (an escape key) will exit the rescue shell successfully.

So verified this bug.
