994342 – Win8-32 guest prompts error 'No such host is known. (0x80072AF9)' when use 'w32tm' to query time

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 CongLi 2013-08-07 05:31:47 UTC

Description of problem:
Win8-32 guest prompts error 'No such host is known. (0x80072AF9)' when use 'w32tm' to query time

Version-Release number of selected component (if applicable):
kernel-3.9.0-0.55.el7.x86_64
qemu-kvm-1.5.2-1.el7.x86_64

How reproducible:
50%

Steps to Reproduce:
1. Boot a Win8-32 guest with CML:
/home/staf-kvm-devel/autotest-devel/client/tests/virt/qemu/qemu \
    -S \
    -name 'virt-tests-vm1' \

    -netdev tap,id=id23RcyP,vhost=on,fd=22 \
    -m 4096 \
    -smp 4,maxcpus=4,cores=2,threads=1,sockets=2 \

    -rtc base=localtime,clock=host,driftfix=slew  \
    -boot order=cdn,once=c,menu=off  \
    -enable-kvm

2. Take a time reading from the guest:
   w32tm /stripchart /samples:1 /computer:clock.redhat.com
 
3. Run a load on host:
   bzip2 -c --best /dev/urandom > /dev/null

4. Take a time reading from the guest:
   w32tm /stripchart /samples:1 /computer:clock.redhat.com

Actual results:
In guest:
The following error occurred: No such host is known. (0x80072AF9)

Expected results:
No error occur.

Can you run ping from guest to out side IP to see how network behaves during host load?

Thanks,
Yan.

And/or please attempt to reproduce with a different network device, such as e1000.

Comment 5 Marcelo Tosatti 2013-08-08 00:58:25 UTC

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 Cong,

Could you have a look commment8 and add your comment?

Best Regards,
Junyi

Comment 11 Miki Mishael 2014-01-12 12:14:13 UTC

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!

Comment 16 Miki Mishael 2014-01-23 10:51:46 UTC

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,

Comment 20 Ronen Hod 2014-01-28 12:47:32 UTC

Mike,

Please try to reproduce and isolate the cause.

Thanks.

Comment 21 Ronen Hod 2014-01-28 14:10:27 UTC

I wonder what the host shows (primarily top).

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

Comment 28 Yossi Hindin 2015-02-19 16:14:25 UTC

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

Created attachment 993689 [details]
Simple NTP client

The ZIP archive contains sources of the simple NTP client.

ntpc core dump

Comment 35 Yossi Hindin 2015-03-05 17:17:59 UTC

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.

      Joseph Hindin
