Hi all,
I have an extrange problem on a rhel5.1 xen host. I have 4 xen guests
running: two para-virtualized and two HVM. Memory asignements are:
xentop - 09:34:05 Xen 3.1.0-53.el5
5 domains: 1 running, 4 blocked, 0 paused, 0 crashed, 0 dying, 0 shutdown
Mem: 3145268k total, 2680980k used, 464288k free CPUs: 2 @ 3213MHz
NAME STATE CPU(sec) CPU(%) MEM(k) MEM(%) MAXMEM(k)

RhelClu01 --b--- 44 0.0 655184 20.8 655360
RhelClu02 --b--- 24 0.0 655224 20.8 655360

My xen host has 3GB of RAM. I need to start up a fifth guest with 512M
of RAM assigned, but I can't because free memory for guests are
464288. But why??
Doing a simple arithmetic operation:
(262192+655184+655224+532352+401280)-3145268= -639036 free memory, but
xentop says that only 464288kb of RAM are free. Where are 174748kb of
RAM that xentop doesn't shows me? Maybe the problem could be this grub
params: kernel /xen.gz-2.6.18-53.el5 dom0_mem=256M
lowmem_emergency_pool=16M [EMAIL PROTECTED]
This reserves 128MB of mem for crash kernel and you would only be able
to see less 128MB from your actual memory on the dom0.
Please I need help.
