RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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):

libguestfs-1.36.2-3.el7.x86_64

How reproducible:

100%

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.

Backported patches are here:

https://github.com/libguestfs/libguestfs/commits/fedora-26

Verified with package:
libguestfs-1.36.10-2.el7.x86_64

Steps:

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.
