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.

And/or please attempt to reproduce with a different network device, such as e1000.
Can you find a message similar to on the event log:
"NtpClient was unable to set a manual peer to use as
a time source because of DNS resolution error on 'time.windows.com,0x9'.
NtpClient will try again in 15 minutes and double the reattempt interval
thereafter. The error was: No such host is known. (0x80072AF9)"
Hi CongLi,
Could you please guide me how to run the auto test, Where can I find the images and the script and if you write few words how to run the setup I will appreciate it.
Thanks!
Hello Cong,
I have access to the guest but is the host on the same location,
ssh -X root.nay.redhat.com?
When I search for qemu-kvm I can't see any processes in top nor for bzip2.
Could you please provide info on the host access, where the script is run from.
Thanks,

Hi,
I failed and I think loading host it the keypoint .Following is my steps:
Scenario1:
steps exactly same as comment #0
Can not reproduce the issue (I think the free memory is too much on my server)
Scenario2:
tried the same steps as comment #0 with win8-64
Can not reproduce the issue
Scenario 3:
Tried all the stpes in comment #0 ,after that
use stress to load the host to use all the free memory
Actual Results:
w32tm prompts 0x800705b4.
I tried to run more times but the host alway hit :Out of memory: Kill process 26825 (sshd) score 0 or sacrifice child
So I ask following needinfo from reporter:
1.Can you try to paste the free -m or top when the bug occurs?
2.Can you try to reproduce this issue on a idle host ?
3.Can you try to reproduce it with IP instead of the domain name on a load host

Hi
It is possible that the issue arise from some networking problem, as opposed to the NetKVM driver in the Windows quest. Please, try to run the program ntpc built from the attached archive on the host or Linux guest in the setup where the issue take place.
ntpc accepts the name of an NTP server like clock.redhat.com and perform simple query similar to w32tm.
Regards,
Joseph Hindin
Sorry, the ntpc programs accepts mandatory argument, name of the NTP host.
like
$ ./ntpc clock.redhat.com
Please let me know if the program crashes with such argument.
Regards,
Joseph Hindin
