Running xen 4.1.1 built from source from xen.org
I''m seeing 2 errors.
during boot get this:

Concerning the enlighten.c error. While it does not seem to cause problems it
concerns me power management may be it''s the real cause network
problems
that are getting my attention.
I got the debian kernel source and line 726 is the line with the *****
static void xen_clts(void)
{
struct multicall_space mcs; *****
mcs = xen_mc_entry(0);
MULTI_fpu_taskswitch(mcs.mc, 0);
xen_mc_issue(PARAVIRT_LAZY_CPU);
}
Means nothing to me :-(
What is it?
What can be done?
Then next one may not be xen but I only had the problem after running a domu.
After a while I get kernel error and networking stops.
This is the error:

Kernel logging (proc) stopped.
In this case dom0 locked up. Some times just networking stops and some times
networking recovers.
Looks like it uses msi-x interrupts.
Concerning igb error I have tried the following one at a time:
New igb driver from Intel site.
kernel parameter pcie_aspm=off
ethtool -K eth0 tx off on dom0
ethtool -K eth0 gro off on dom0
It has never died doing iperf from dom0 or domu <> external.
Never died during network backup.
Usually takes a least a few hours and has never made it a day running a domu.
Wish I could get it to die faster :-)
Any ideas?
I''m pretty much down to trying different network cards
Any ideas?
John

Did that make any difference?> > Any ideas?There is a Xen parameter called ''noirqbalance'' . Try that. Also see if you can limit the CPUs in the dom0 using these two arguments on Xen hypervisor: dom0_vcpus=2 dom0_vcpus_pin=1 It would be interesting to narrow down _when_ you trigger this failure. B/c we can pull Xen to see what the MSI''s are ''xl debug-keys M'' _before_ and _after_ your failure to see if something is amiss. Mainly to figure out if the vectors are moving around the CPUs (or not) (XEN) MSI 29 vec=21 lowest edge assert log lowest dest=00000001 mask=0/0/-1 and also ''xl debug-keys i'' to see if the domain has ACK-ed the interrupt: (XEN) IRQ: 29 affinity:00000000,00000000,00000000,00000001 vec:21 type=PCI-MSI status=00000010 in-flight=0 domain-list=0:275(----), (the last ''----'' might have something else in in them - if so that is a sign that dom0 hasn''t picked up the event/vector). _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

About 10 minutes after removing irqbalence I lost networking. I''m remote and few minutes later lost ipmi sol so odds I lost the serial port interrupt also. So went to ikvm. Was able to able to restore network with ifdown xenbr0 rmmod igb modprobe igb ifup xenbr0 The runnning domu still had no networking. Attached is dom0.dmesg.gz dom0 dmesg I see nothing in particular myself. xen.dmesg.gz xl dmesg I had done the M and i earlier and ran them just before running xl dmesg so it should have before and after. Did these before bringing the network back up. I''ll reboot and run as you requested. John _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Konrad I ran as you requested and after 2 days it''s still up. Attached are xen.dmesg and dom0.dmesg all the command line parameters are in them. At this point I''d be happy if was on line with a reasonably efficient stable configuration. Supermicro has been helpful on other issues but not with this. Suspect I''ll need to have some idea what the problem is to be able to get it sent to the right person. Any suggestions?

Do you have another of these > boxes available remotly to debug this further?Konrad Just one box but I''m willing to try more things. A shame this is otherwise a really nice box for the price. I sent Supermicro another email with updated info. I''m not holding my breath :-( They did fix the ipmi firmware for me so I guess I can hope for a fix. In my last test shouldn''t dom0_vcpus=2 have been dom0_max_vcpus=2? Dom0 still has 16 cpus. I''d prefer not pining dom0 but stability is more important :-) Thanks for all the help so far.
