[Xen-devel] CE: xen increasing min_delta_ns to 14866484018615571080 nsec
Hi, I often have this problem on a PV DomU : [9223372308.932175] CE: xen increasing min_delta_ns to 14866484018615571080 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 13076353991068580812 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 1167786912893319602 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 10975052406194755210 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 7239206572437357006 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 10858809858656035508 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 16288214787984053262 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 5985578108266528276 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 18201739199254568222 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 18079236762027076524 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 8672111069331063170 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 3784794567141818946 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 5677191850712728418 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 8515787776069092626 nsec [9223372308.932175] CE: xen increasing min_delta_ns to 12773681664103638938 nsec The Dom0 kernel is a 64bit pv_ops, the "new" 2.6.32 from Debian sid, and I had same problem with my previous vmlinuz-2.6.31.6-dae-dom0-00751-g60e0545. I use Xen 3.4.3 (rc3). And on the DomU, it''s a vanilla 2.6.32.9 kernel. This VM have 4 VCPU and near 8G of RAM. Any idea ?

Could you try that out? Thanks, J _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
