Hey all,
I have a xen server setup and running version 3.4.2. Kernel version is
2.6.31.12.
My issue here is that when I do a free -m within the Vm is shows less, some
times more ram then what the config files shows. Here is an example of what I
see from xend starting the domU.
[2010-03-14 17:09:45 2598] DEBUG (balloon:166) Balloon: 7766704 KiB free; need
526336; done.
When I do a free -m within the domU I get it showing me a total of 506mb.
when I do cat /proc/meminfo is shows a total of 518220
why so many different numbers? Config options below.
Made the dom0 and domU kernel by doing
git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git
linux-2.6-xen
cd linux-2.6-xen
make && make modules && make modules_install && make
bzImage && make install
my domU config is
kernel = ''/boot/vmlinuz-2.6.31.12-XenDom0''
ramdisk = ''/boot/initrd.img-2.6.31.12-XenDom0''
memory = ''512''
#
# Disk device(s).

root = ''/dev/xvda2 ro''

]

name = ''Testing''

vif = [ ''ip=204.124.181.72,mac=00:16:3E:78:FB:92'' ]

It would appear that for what ever reason my system is off by 19MB. I had to
set my testing.cfg file to 531MB to get free -m to show 512mb of total memory.
can anyone provide any insight as to why or where i may go in an attempt to get
this solved? 20mb adds up to a lot when you run several domu''s

It would appear that for what ever reason my system is off by 19MB when it comes
to 512mb, and 28mb per gb. I had to set my testing.cfg file to 531MB to get
free -m to show 512mb of total memory and 1052 to get it to so show 1024.
can anyone provide any insight as to why or where i may go in an attempt to get
this solved? 20mb adds up to a lot when you run several domu''s
