CentOS 5/6 guest network receive path fails with Xen 4.1/Fedora 16 Dom0
(XEN) traps.c:3004: GPF (0060): ffff82c480153ed9 -> ffff82c480201488
Solution
This issue seems to be resolved by the patch 'xen/netback: calculate correctly the SKB slots'. Patch the linux-3.4.4-5.fc17 source RPM and generate a new kernel RPM.
Note: The patch appears to be in kernel 3.5rc7, but not kernel 3.4.6.
Issue
This is a capture of my notes trying to problem solve an issue.
Symptoms
- Dom0 and DomU keep running with no error messages
- Network packets from DomU through Dom0 keep being forwarded
- Network packets going through Dom0 to DomU never reach DomU
- The console and disk I/O are fully operational
Executing the following command (as per this list item) causes the same or similar problem:
$ ping -s 3991 -c 128 <hostname>
The host seem to last about 16 pings before network connectivity is lost.
Environment
- all 64bit
- Fedora 16
- xen-4.1.2-7
- 3.4.2-1.fc16.x86_64
- AMD Opteron 2000 CPU
- NVidia MCP55 chipset
- Network
- nVidia forcedeth ethernet
- 9k frames
- ipv4 and ipv6
- bond interface (LACP), with VLANs
- bridge (setup with Fedora network scripts)
Failed approaches
- Upgrade to the latest code (xen, dom0 & domU)
- Enable logging
- Upgrade BIOS
- disable offload support in domU
- leave a ping running to keep the network 'hot'
- Disable IOMMU
- Generate traffic from the inside and/or outside
- remove and then re-add the VIF interface to the bridge in domU
- enable irqbalance in dom0
- disable irqbalance in domU
- enable irqbalance in domU
- add serial port to Xen host to capture additional information (over and above xl/xm dmesg output)
- using 'xl' to network-detach and then network-attach a new VIF (but 'xm' was ok)
- reinstall the VM from CentOS 5 to CentOS 6 and hope it doesn't happen as often
- post to xen users list
- reinstall Dom0 with Fedora 17 (xen-4.1.2-20.fc17, kernel-3.4.4-3.fc17)
Best workaround(s)
- Restart the VM
- Use 'xm network-detach' and 'xm network-attach' when the fault occurs
Restarting the VM is easy to do manually by logging in via the console, and then issuing a command to reboot. Using 'xl' to detach the VIF network interface didn't work, so the legacy 'xm' command was used successfully.
ToDo/Future
- Xen 4.2 (not released yet)
Issues
3 issues have been identified:
- receive path packet loss on Centos 5/6 VM's (two CentOS 5 VM are the main issue, one is a Nginx reverse proxy and the other is a Samba server)
- 'GPF 60' from unidentifed domains(s)
- 'Domain attempted WRMSR' from CentOS 6.x domains
GPF 60
No idea what this is, or which virtual machine(s) are generating it.
Domain Attempted WRMSR
This seems to be a known issue that can't be seen in Bugzilla 477647. This thread indicates it relates to "performance monitoring MSRs".
Links
- Kernel panic with 2.6.32-30 under network activity

Appendices
Only non-freed SKB is queued into tx_queue
Posted to xen-devel and netdev mailing list.
After SKB is queued into tx_queue, it will be freed if request_gop is NULL.
However, no dequeue action is called in this situation, it is likely that
tx_queue constains freed SKB. This patch should fix this issue, and it is
based on 3.5.0-rc4+.
This issue is found through code inspection, no bug is seen with it currently.
I run netperf test for several hours, and no network regression was found.
