Can you run ping from guest to out side IP to see how network behaves during host load? Thanks, Yan. (In reply to Yan Vugenfirer from comment #3) > 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. 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 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, Mike, Please try to reproduce and isolate the cause. Thanks. I wonder what the host shows (primarily top). (In reply to Ronen Hod from comment #20) > Mike, > > Please try to reproduce and isolate the cause. > > 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 (In reply to Mike Cao from comment #23) > (In reply to Ronen Hod from comment #20) > > Mike, > > > > Please try to reproduce and isolate the cause. > > > > Thanks. > > Hi, > > I failed and I think loading host it the keypoint .Following is my steps: I mean I failed to reproduce it .. > 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.

Simple NTP client
The ZIP archive contains sources of the simple NTP client.

ntpc core dump
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 Is this BZ still relevant today? I am closing it, please reopen in case it is still relevant. |
