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 tingting zheng 2013-03-01 07:54:55 UTC 
Description of problem:
Incorrect error messages showed when --disk parameter contains special characters

Version-Release number of selected component (if applicable):
python-virtinst-0.600.0-15.el6.noarch
libvirt-0.10.2-18.el6.x86_64
virt-manager-0.9.0-18.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Add special characters to --disk paramter,eg:"#","%","!"
# virt-install -n test  -l http://download.englab.nay.redhat.com/pub/rhel/rel-eng/latest-RHEL-6/6.4/Server/x86_64/ --disk /var/lib/libvirt/images/test#test.img,size=3G --ram 512 --graphics vnc

# virt-install -n test  -l http://download.englab.nay.redhat.com/pub/rhel/rel-eng/latest-RHEL-6/6.4/Server/x86_64/ --disk /var/lib/libvirt/images/test!test.img,size=3G --ram 512 --graphics vnc
-bash: !test.img,size=3G: event not found

Actual results:
Incorrect error messages showed when --disk parameter contains special characters

Expected results:
Correct error messages showed,if can not add these special characters on --disk,right prompt showed.

-bash: !test.img,size=6: event not found

Seems only the third one is fixed,other three issues are not fixed,so move back to ASSIGNED.
Comment 6 Martin Kletzander 2013-07-22 08:39:03 UTC 
What is the output if you prepend 'echo' before the first and second command?

Output of the third command hadn't changed, the 'size=3G' was invalid in the description, virt-install only supports numbers without suffixes to specify the size of the volume.

There is no error in fourth command as the error message comes from your shell (hence the 'bash:'), exclamation mark is an operator (and a great one actually), see "HISTORY EXPANSION" section of bash(1) manual.

Yes,the third command has fixed if I use size=3,refer to comment 5 error.

So does it mean no need to fix the fourth command from python-virtinst?
Comment 8 Martin Kletzander 2013-07-22 11:37:55 UTC 
I've found out the problem for those first two, I forgot to backport one missing patch, thanks for helping out.  The fix will be in next package.  Nothing to fix in the fourth command, if you want to add an exclamation mark you must escape it, either as:

virt-install -n test1  -l http://download.englab.nay.redhat.com/pub/rhel/rel-eng/latest-RHEL-6/6.4/Server/x86_64/os/ --disk /var/lib/libvirt/images/test22\!test.img,size=6 --ram 512 --graphics vnc

or:

virt-install -n test1  -l http://download.englab.nay.redhat.com/pub/rhel/rel-eng/latest-RHEL-6/6.4/Server/x86_64/os/ --disk '/var/lib/libvirt/images/test22!test.img,size=6' --ram 512 --graphics vnc
