Yingfu, If it's reproducible, why not attach gdb to the process and see where it fails? Add kvm-debuginfo package, and you've made the developer's life much easier. Created attachment 339277 [details]
trace message from dmesg
Yaniv, attachment is the trace message from dmesg on host, sorry for attach it a little late. :)
There is no backtrace in gdb since it did not crash the guest,which means although we can find the trace message in dmesg on host, the guest is running well.
The command I used:
#qemu-kvm /tmp/kvm_autotest_root/images/RHEL-Server-5.3-64.qcow2 -smp 4 -pcidevice host=00:1c.0 -m 1000
Tested kvm pkg: 83-28
pci passthrough is not supported for rhev (only for rhel 5.4) btw: there is no kvm rpm ver. Can you close the bug? Development Management has reviewed and declined this request. You may appeal this decision by reopening this request. RE: comment #3, llim->yzhou, please create the bug against RHEL5.4 (In reply to comment #3) > pci passthrough is not supported for rhev (only for rhel 5.4) > btw: there is no kvm rpm ver. > Can you close the bug? Hi Dor, I had added kvm rpm version when the bug was opened: -------- Version-Release number of selected component (if applicable): 83-20 <<<<<<<<<<< version is here kernel : 2.6.18-128.el5 #1 SMP Wed Dec 17 11:41:38 EST 2008 x86_64 x86_64 x86_64 GNU/Linux cpu: Intel(R) Core(TM)2 Duo CPU E6550 -------- Ok, Lawrence, I will create it against 5.4. Thank you! :) Dor: Does the configuration flags needed by PCI-passthrough (such as CONFIG_DMAR) is turned on in RHEL5.4 or there is some others flags used to do this? I could not found any flags related to passthrough in current kernel of RHEL 5.4(2.6.18.138.el5). Support for PCI pass through is a feature for Version 2.0 so this is a bug which has to be fixed. Reopen bug n adjust flag. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. On RHEL-6, the KVM userspace package is named "qemu-kvm". Moving bug to the right component. This issue is not found in qemu-kvm-0.12.1.2-2.36.el6.x86_64, so setting status to verified. |
