kernel panic occurred when boot up rhel3.9-64 with virtio block and 2vcpu
Last modified: 2010-11-11 14:30:30 EST
Created attachment 432035 [details] screenshot Description of problem: Install the rhel3u9 VM with ide disk and 2 vcpu, and update the kernel to 2.4.21-63-smp, then install kmod-virtio-smp-0.1-17.el3.x86_64.rpm, boot up VM with virtio disk again. VM kernel panic occurred. Version-Release number of selected component (if applicable): host: kernel 2.6.32-44.1.el6.x86_64 qemu-kvm-0.12.1.2-2.91.el6.x86_64 guest: kernel 2.4.21-63-smp How reproducible: 100% Steps to Reproduce: 1.Install the rhel3u9 VM with ide disk and 2 vcpu 2.update the kernel to 2.4.21-63-smp 3.install kmod-virtio-smp-0.1-17.el3.x86_64.rpm 4.boot up VM with virtio disk Actual results: VM kernel panic Expected results: can boot up with virtio driver Additional info: cmdline: /usr/libexec/qemu-kvm -S -M rhel6.0.0 -enable-kvm -m 2048 -smp 1,sockets=1,cores=1,threads=1 -name kernel-r3.9-64 -uuid 587000c4-e53c-45bd-f237-49b7fe78081e -nodefconfig -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/kernel-r3.9-64.monitor,server,nowait -mon chardev=monitor,mode=control -rtc base=utc -boot c -drive file=/home/images/kernel-r3.9-64.img,if=none,id=drive-virtio-disk0,boot=on,format=raw,cache=none -device virtio-blk-pci,bus=pci.0,addr=0x6,drive=drive-virtio-disk0,id=virtio-disk0 -netdev tap,fd=16,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:5d:21:7c,bus=pci.0,addr=0x4 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -vnc 127.0.0.1:2 -k en-us -vga cirrus -device AC97,id=sound0,bus=pci.0,addr=0x5 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3
The kernel boot parameters will have to be modified to boot from /dev/vdaNN. Also, you will have to make sure the virtio drivers are present in the initrd.img file, otherwise the kernel won't be able to find the virtio drivers and won't be able to detect the disk.
This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. **
(In reply to comment #2) > The kernel boot parameters will have to be modified to boot from /dev/vdaNN. I boot up with smp=1 + up kernel, and didn't modify the kernel line, it is boot up successfully. But failed smp=2 + smp kernel. I will try /dev/vdaNN.
Please try refreshing the initrd for the smp kernel, be sure it includes the virtio block driver, and try again.
I refreshed the initrd for the smp kernel, and can boot up VM with virtio_blk driver. So it is kmod-virtio package for smp kernel initrd issue, I will create a new bug for this component. #mkinitrd initrd-2.4.21-63.ELsmp.img.gyue 2.4.21-63.ELsmp --with=virtio --with=virtio_net --with=virtio_blk --with=virtio_pci --with=virtio_ring Closed this bug as this is rhel3 virtio component issue.
