Description Lingfei Kong 2014-10-15 03:07:08 UTC

Description of problem:
Currently if i want to end a running commands, these commands often can not finish correctly, the only way is to exit virt-rescue. If the commands have a acceptable time to return, then i can wait until it return. But if the commands can not return when it run incorrectly or have a very long time to return, then i have to quit virt-rescue to end that commands.
If i use virt-rescue to fix a bad virt machine, there is a high probability to encounter this situation.


Version-Release number of selected component (if applicable):
libguestfs-1.27.62-1.1.el7


How reproducible:
100%


Steps to Reproduce:
1. Get a rhel guest image: rhel.img
2. #virt-rescue --network -a rhel.img
><rescue> ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
3. Press ^C


Actual results:
><rescue> ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
qemu: terminating on signal 2

^C will let you exit virt-rescue

Still a bug even upstream, but moving to 7.4.

Comment 5 Richard W.M. Jones 2017-02-16 17:04:55 UTC

This is an upstream bug that probably won't affect RHEL customers
very much.  Let's track this upstream instead.  (It's also really
a bug in qemu, not libguestfs)
