I just migrated a W2K3 Server to a Xen HVM domain, using the gplpv 0.10.69 drivers. Now ping shows strange results: Pinging 127.0.0.1 with 32 bytes of data: Reply from 127.0.0.1: bytes=32 time=23538ms TTL=128 Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Reply from 127.0.0.1: bytes=32 time=-23538ms TTL=128 Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Same result with external addresses (which I checked first, when I found that iScsiInitator doesn''t work any more) Apparently the xen pci driver also installs the "High precision event timer", so I suspect a misbehaviour in the gplpv driver. Any clues? Regards, Andreas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
