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:
Can't set the timer base as localtime once localtime is used in the variable attribute.
Version-Release number of selected component (if applicable):
# rpm -qa libvirt qemu-kvm
qemu-kvm-1.5.3-30.el7.x86_64
libvirt-1.1.1-16.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1.Add the following element in the healthy domian
<clock offset='variable' adjustment='3600' basis='localtime'/>
2.# virsh start rhel
error: Failed to start domain rhel
error: unsupported configuration: unsupported clock basis 'localtime'
3.
3.1In libvirt.org, here's the description "Since 0.9.11 the basis attribute can be either 'utc' (default) or 'localtime'. "
3.2# man qemu-kvm | grep localtime
-rtc [base=utc|localtime|date][,clock=host|vm][,driftfix=none|slew]
Specify base as "utc" or "localtime" to let the RTC start at the current UTC or local time, respectively.
3.3 change the clock setting as <clock offset='localtime'/>, start the guest. The base is set as localtime in the qemu cml.
# ps -aux | grep win| grep rtc
...-rtc base=localtime
Actual results:
Can't set the timer base as localtime once localtime is used in the variable attribute.
Expected results:
From step 3, localtime base should be supported.

qemuxml2argvtest: Test localtime clock basis
When trying to introduce a test for previous patch, I've
noticed that the command line is constructed using current
time. This won't work in our test suite (unless you guys
wants to set a specific time prior to each test run :) ).
Therefore we need to mock calls to time(2) to return the
same value every time it's called.

qemuBuildClockArgStr: Allow localtime clock basis
https://bugzilla.redhat.com/show_bug.cgi?id=1046192
Commit b8bf79a, which adds clock='variable', forgets to check
localtime basis in qemuBuildClockArgStr(). So that localtime
basis could not be used.
