On a selection of boxes, ntpd running in Xen Dom0 reproducibly exhibits extermely high noise/jitter. Switching back to -default, non-xen kernel ntpd runs with very low jitter/noise. Question -- how can I ''tame'' ntpd noise & jitter when running in Dom0? Is the problem a config issue, or a bug? Already reported this downstream; everybody''s "stumped".

Hi experts, Q1:What''s the different for "dom0_max_vcpus=4 dom0_vcpus_pin" and "dom0_max_vcpus=4" ? which will get better performance Q2: dom0_max_vcpus=4 means "core0-3 will be just used by dom0" or means "4 cores(not dedicate cores) will be used by dom0, eg: core2-5 or core3-6? Q3.what does mean "nosmp" , xen, dom0,domU, will just use one

I''m getting the error: xend (12, ''Cannot allocate memory'') From the command line after the Dom-0 goes through a period of heavy memory usage.

Hi, > Can you manually do on the xen interfaces what the scripts would? How about > doing it on some other interface configured in a similar way? Toying with the vif-route script, I might have found a workaround for this issue. If I disable the ifconfig and ip route commands from vif-route script, and bring up vif interface by hand later on, everything seems to work. In other works,

Hello everyone! With the completion of our first few release candidates for 4.2, it''s time to look forward and start planning for the 4.3 release. I''ve volunteered to step up and help coordinate the release for this cycle. The 4.2 release cycle this time has been nearly a year and a half. One of the problems with having such a long release is that people who get in features

Hello, Jeremy: See the included patch. If it''s OK it''d be nice to get it into xen/stable-2.6.32.x branch.

I''m having issues with HVM live migration and every xen version I''ve tried - 3.0.1, 3.1.x, 3.3.0 and 3.3.1.

Hi all, after installing the driver ( I used the Vista-2008-Debug version) and rebooting, the system presents me an interface for recovering the OS using an image. I use Xen 3.3.1 Is there a workaround? Thanks and regards, Francesco Gallo _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

I''ve just uploaded a new binary release of the GPL PV drivers for Windows - release 0.6.3. Fixes in this version are: . Should now work on any combination of front and backend bit widths (32, 32p, 64). Previous crashes that I thought were due to Intel arch were actually due to this problem. . The vbd driver will now not enumerate ''boot'' disks (eg those normally serviced
