Re: [Xen-devel] Xen3.1 network freeze with IPMI
Hi Marek,we are using IPMI with Scientific Linux CERN 4. It is built on the same code base as RHES4.
On one of the test machines has a supermicro chip and runs Xen 3.0.4.As far as I can say IPMI works fine when using the local interface from within the machine. I was not able to get IPMI working over the LAN interface. But I'm working on that.
A former colleague who investigated and set up IPMI on our machines also reports some problems with XEN in conjunction with IPMI:

hi,i am using supermicro with remote management IPMI (http:// www.supermicro.com/manuals/other/SUPER_IPMI_2.0.ppt) IPMI card has own MAC adress and IP address (but ethernet cable is shared)i am using xen 3.1 from www.xensource.com (on centos5.0)if IPMI card is "freezed*" (cannot connect to IPMI) then xen3.1 kernel(NETWORK) works fineif i do "mc reset cold" from host system then NETWORK freeze (but IPMI works) i can connect with IPMI to the system. dmesg,messages,ifconfig all looks ok but network do not work. /etc/init.d/network restart does not help, i must restart whole serverping from this machine ends with PING <other ip> 56(84) bytes of data.From <server ip> icmp_seq=0 Destination Host Unreachablethis is strangeserver without IPMI works fine. server with IPMI without XEN kernel works fine. (IPMI does not like XEN and backward)do you have idea what is the problem?* IPMI card sometimes freeze and is unreachable. it must be restarted :(--------------------------------------- Marek Cervenka ======================================= _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
