Thanks for your reply. Due to the RHEL 6.4, this driver, 3.1-1.1.0.1, is latest suitable one. The 3.3… driver doesn’t support RHEL 6.4. I was not at the scene temporarily, when I am back, I will try to catch the messages.
Thanks. I didn’t find anything about crash. Maybe I should say I don’t know what I should look. Do you have any ideas about this? Where can I find logs/ error files etc… Which files are helpful to this issue?
On the other side, I always doubt there are some wrong settings. If you also think so, which setting should I check?
BTW, I found this post
SR-IOV issues with Mellanox CX-3 with RH6.4 KVM
but in this post, the host did not crash, the problem is just the guest cannot start…and this post mentioned the kernel should upgrade…
You’re using relatively old driver and FW. Any reason for that? If no, can you upgrade them?
Also, please attach dmesg output (you can use netconsole to keep it logged on a different server, or keep another shell opened and tail /var/log/messages).
