Re: [Xen-users] Memory consumption of xend on x86_64

[Rob Aronson <riaronson@xxxxxxxxx>]

I think you can l limit the amount of ram consumed by dom0 on 64 bit hosts by modifying the kernel initialization statement in grub or lilo. just add the line dom0_mem=512M or something similar. You can also change the memory after initialization by running xm mem-set 0 512M and it should change dom0

Hi,

On one of our servers which has 6GB RAM (dom0 RAM: 3GB), the xend service
is taking about 46% of the memory. Is this normal? We use xen on other
servers (8GB, 6GB RAM) too and in them xend is taking about 3% of the
memory.

This particular server if of x86_64 architecture where as the rest are of
i386. Is that the reason for xend taking so much RAM?
