Re: [Xen-users] Random dom0 lock up

Just use "mem=4095M" instead of "dom0_mem=4095M" in the xen.gz line.

Hi,

Im not sure how else to limit it to 4g? In the kernel command line i have 


title           Xen 4.0 / Debian GNU/Linux, kernel 2.6.32.13
root            (hd0,0)
kernel          /xen.gz dom0_mem=4095M
module          /vmlinuz-2.6.32.13 root=/dev/md1 ro console=tty0
module          /initrd.img-2.6.32.13

when you say the whole hypervisor, where else are you setting the limit?

Thanks

Ian

I meant limit it to less than 4G.  And by "it" I mean the whole hypervisor, not 
just dom0.  Solved all my issues.

Hi,

Its 32bit.  Currently i have it set to 512mb.  So setting it to 4095 might 
help? I will try that when i get back to the office.

On another note is there a way to capture the errors without using a serial 
console? The reason i ask is we are not allowed physical access to our kit in 
the data center which obviously complicates things somewhat.

Thanks

Ian

32 or 64 bit?  One of my newer quad-core boxes had a ton of stability problems 
running 32bit with 4G of RAM.  Telling the hypervisor to only use 4095M made 
things work much better.  Try adding "mem=4095M" to the hypervisor command line.
