Re: Latest Centos6.3 kernel, rebooting from inside centos6.3 VM - gets stuck on seabios/grub loop - previous kernels fine
Marcelo your awesome ! thank fixed it. Thank you. Is this an issue just with centos kernel or is rhel effected also ? i.e shall I submit a bugzilla report?

Ubuntu 12.04 (kvm host) Centos6.3 (guest) , rebooting from inside centos6.3 VM - gets stuck on seabios/grub loop - previous kernels fine - occurs on multiple servers
I have a really annoying bug, I can reproduce often (although it is a bit random). I have an Ubuntu 12.04 KVM server , using Centos 6 guests - when I install the latest kernel for centos 6.3 -2.6.32-279.1.1.el6 - if you reboot from inside a Centos6 vm it gets stuck in a loop between seabios/grub - this does't happen 100% of the time - there is a high chance it will though - usually after 3 reboots it will get stuck in the loop - it will NEVER reboot without manual intervention (virsh destroy..) It seem to fail at the kernel initialise stage - if I use vga=normal I can see the words 'Probing EEID...' for a sec (then it reboots) If i use virsh/virt-manager to reboot its fine, only from inside a centos6 vm (with latest centos kernel) does this occur As a test I installed centos 6.2 - this was 100% fine *until* I did a yum update then I got the same issue. Ubuntu 10.04 KVM host / Centos 6.3 (guest) is fine - so i'm unsure where the fault is. Likewize a Centos 6.3 kvm host and centos 6.3 guest is also fine... I have installed a 2nd Ubuntu 12.04 KVM server and the exact same thing occurs (i.e 2 different servers = same issue) How can I troubleshoot this ? I already have already enabled the boot (options 'console=ttyS0' (which I can access vm's using virsh console id) however this gives no output (as it crashes when initialising the kernel) I have also tried installing the latest qemu-kvm (1.1) from source on the Ubuntu 12.04 kvm server, the same thing occurs . I have reported bugs @ Ubuntu and Centos (only Ubuntu have bothered to respond) https://bugs.launchpad.net/centos/+bug/1025188 http://bugs.centos.org/view.php?id=5841 There is a vid showing the issue here https://launchpadlibrarian.net/110374291/out.ogv (you can't see the boot msgs as I am using console=ttyS0 on the boot options) Any info, help, hints at where to look next would be useful Regards -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
Latest Centos6.3 kernel, rebooting from inside centos6.3 VM - gets stuck on seabios/grub loop - previous kernels fine
Hi I have an Ubuntu 12.04 KVM server In Centos6 VM's - when I install the latest kernel for centos 6.3 - 2.6.32-279.1.1.el6 - if you reboot from inside a Centos6 vm it gets stuck in a loop between seabios/grub. If i use virsh/virt-manager to reboot its fine, only from inside a centos6 vm (with latest centos kernel) does this occur - I am 100% its connected with the latest kernel (or at least the 6.3 updates). As a test I installed centos 6.2 - this was 100% fine *until* I did a yum update then I got the same issue. If I use the older kernel with all the rest of the Centos 6.3 updates the issue does not occur either (so it 'must'? be related to the kernel update) How can this be fixed ?
