[Xen-devel] [SPAM] pvops 2.6.32.23 failed to boot due to balloon.c

[Jia Rao <rickenrao@xxxxxxxxx>]

Hi all,

I tried xen-4.0.2-rc1-pre with pvops 2.6.32.23 kernel. The linux kernel failed to boot due to something wrong in driver/xen/balloon.c

Limiting dom0_mem=2048M solved the problem. 

FYI. 

Dell PowerEdge 1950 III

Intel Xeon E5450 quad-core CPU

8G memory

dom0: CentOS 5.4 

The following is the console log from the failed boot. Search for balloon.c, you will locate the failed calltrace.

Thanks,

Jia
