[Xen-users] Problem with Broadcom Corporation NetXtreme II BCM5708 bnx2
Hi, I have a Dell PowerEdge 1950 with two NICs Broadcom NetXtreme II BCM5708 1000Base-T. I installed CentOS 5.1 and Xen 3.0.3 (RPM). One of my virtual machines has Windows 2003 Server. In this virtual machine my NICs appears like "Realtek RTL8139 Family PCI Fast Ethernet NIC". The problem is that when I ping to other machines sometimes the reply time value is very high: C:> ping 10.1.1.1 Reply from 10.1.1.1: bytes=32 time<1ms TTL=127 Reply from 10.1.1.1: bytes=32 time<1ms TTL=127 Reply from 10.1.1.1: bytes=32 time<1ms TTL=127 Reply from 10.1.1.1: bytes=32 time=-29815ms TTL=127 Reply from 10.1.1.1: bytes=32 time<1ms TTL=127 Reply from 10.1.1.1: bytes=32 time<1ms TTL=127 Reply from 10.1.1.1: bytes=32 time=-298341ms TTL=127 Reply from 10.1.1.1: bytes=32 time<1ms TTL=127 Reply from 10.1.1.1: bytes=32 time=29382ms TTL=127 Reply from 10.1.1.1: bytes=32 time<1ms TTL=127 It important to indicate that the "real" time is good ( approximately between 1 and 2 seconds ). The problem is some applications used this value to monitor some servers and send alarms when time value is high. How you can see some time the reply value is negative. The problem is only with virtual Windows machine. What can I do? Some idea? Thanks a lot for your help Roberto _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, I ran into trouble with this NICs a few times, too. Be sure you have a new driver version. I don''t know which version Xen 3.0.3 RPM delivers. Couldy you tell me? And perhaps you should give James Harpers Paradrivers a chance. Cheers, Alex rem@ulsa.mx schrieb:> > Hi, > > I have a Dell PowerEdge 1950 with two NICs Broadcom NetXtreme II > BCM5708 1000Base-T.

Some idea?Sounds like you have a clock problem to me. Have you tried disabling acpi in the VM definition? There''s also something called timer_mode, but good luck finding any documentation about it (like a lot of other Xen stuff). -- Jefferson Ogata : Internetworker, Antibozo _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

RE: [Xen-users] Problem with Broadcom Corporation NetXtreme II BCM5708bnx2
Hi all I finally found the way to solve my problem. I install my windows virtual machine using the guide on http://wiki.xensource.com/xenwiki/HowToXenWindowsOnCentOS5 The last time I did the installation using the "Virtual Machine Manager" but now I do it using virt-install and when ping to other machines the time is good. Maybe a bug in VMM? I don''t know but now with virt-install I can use without problems my virtual machine.
