boot stops after console handover?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Hi,

Trying to boot KVM on a Core2Duo system, kvm-59 + linux-2.6.23.12 Booting with:
qemu-system-x86_64 -hda /home/uml/BusyBox-1.5.0-amd64-root_fs -m 384
- -nographic -cpu qemu64 -kernel /boot/vmlinuz-2.6.23.12 -append "earlyprintk=serial,ttyS0,115200"

Boot stops after:

[    0.509283] time.c: Detected 2393.985 MHz processor.
[    0.600090] Console: colour VGA+ 80x25
[    0.600570] console handover: boot [earlyser0] -> real [tty0]

It sits there using 100% CPU until I kill it.

If I add "-serial file:serial.log", I get dropped to the qemu shell and the log file contains the same as above.

Sorry if this has been covered before, couldn't find it.

Cheers
Antoine

Am I being unlucky, doing something wrong or do you need a more specific configuration to get kvm working?

Does regular boot (without -kernel) work?

error compiling committee.c: too many arguments to function

Nope, it's just spinning at 100% cpu, tried stock 2.6.23.12 and 2.6.24-rc6, lots of clock_gettime(CLOCK_MONOTONIC,...

Do I need to enable/disable some RTC / HPET options?

this is a big guess as I have no way to test it or know the internals well enough to come with an authoritative answer, but I remember having a similar problem once which was fixed by using the kernel option "nolapic"

there used to be a bug about it before which was closed by the reported even though I was able to reproduce it after all (haven't looked since) and it was related to the use of CONFIG_HPET_EMULATE_RTC=y in the guest kernel.

sorry for not giving you any hard evidence, but I am just going from memory here and though I would mention it just in case it could help.

I assume this is for the host? (no effect on the guest) unfortunately that box won't boot with nolapic, the sata controllers timeout. (although I haven't tried turning apic off in the bios)

I've disabled that, and everything else I could trim. Still no luck :(

Thanks, much appreciated.

gdb gives me this, dunno if this helps:

Which is this:

where
        int fd = kvm->vcpu_fd[vcpu];

It's worth trying. If that doesn't work, maybe you can upload an image for me to debug.

Any luck? Any other ideas for me to try?

Haven't got around to it yet, sorry.

Probably harmless, but worth reporting to lkml.

Any sufficiently difficult bug is indistinguishable from a feature.

couldn't replicate it here, but I'd seen usually those kind of errors when building a kernel that hasn't been "mrproper" between re-configurations

make oldconfig # presumed

replicated with your configuration, but can't still reproduce it with mine even when forcing as you do

CONFIG_KVM=y
CONFIG_KVM_INTEL=y

available from :

http://tapir.sajinet.com.pe/kvm/config-2.6.24-rc7-git4

is this the configuration for the host kernel?

if you want to use the last code for kvm you should have CONFIG_KVM disabled and instead use the external module as instructed in (HINT: you don't have a patched kernel) :

http://kvm.qumranet.com/kvmwiki/HOWTO1

not sure which version will be part of 2.6.24 but I suspect it might not be kvm 59.

Carlo

see if the problem goes away with -no-kvm-irqchip and using "nolapic" in the guest kernel

if that doesn't fix it, use the last kvm code as an external module

All good now.

FYI: Once I got the console output after boot using a cmdline like "earlyprintk=serial,ttyS0,115200,keep console=ttyS0,115200" I found that the kernel was spinning, failing because of some problem with the fstab or something like that (can't remember now.. need sleep) That's using 2.6.24.2
Note that I have to use the '-kernel' switch otherwise it doesn't work.

Cheers
