Re: Guest OS crash unexpectedly

Memory on your system is divided to 3 zones: DMA, 0-16MB, normal, 16MB-830MB, and high, 830MB-end of physical memory. And some device driver you are using (disk driver? network card?) allocates all memory from DMA zone, and wants even more. And when your kernel sees that, it decides to kill biggest application you run - vmware-vmx...

You can free DMA zone by not using SuSE kernel... these problems were reported with SuSE kernels only...

After modifying the memory setting for the VM and set the memory to reserved Host Physical RAM, That solves my problem.

What makes the difference in the memory and how the DMA Zone get free up?? Can you please explain on this.

You are running out of memory in DMA zone. If putting higher number into min_free_kbytes did not help, I'm afraid that you'll have to use normal kernel instead of SuSE one - I'm quite sure that if you'll use 2.6.10 from www.kernel.org without patches, it will work much better.

Guest OS crash unexpectedly

sarge — Wed, 07 Dec 2005 07:55:04 GMT

Host OS running SLES 9 Kernel version 2.6.10
GSX server 3.2 build 14497

we want to run 2 SAP-Systems on GSX Server at the same time.

One Guest-OS with startet SAP-System is not the problem. It runs
unimpeachable.

If i start the second Guest-OS an start the SAP-System, the first startet
Guest-OS crashed.

Also tried modifying /proc/sys/vm/min_free_kbytes by adding 'echo 8192 > /proc/sys/vm/min_free_kbytes'
doesn't solves the problem.

Any ideas!!!
