Hi all:
I encountered a troublesome problem about OVMF.
I used OVMF.fd as a BIOS of virtual machine(VM).
1、my environment:
xen_version : 4.6-unstable
I git clone xen from git://xenbits.xen.org/xen.git. configure it and
parameters as below:
./configure --prefix=/usr/ --libdir=/usr/lib/ --enable-ovmf then make
&& make install, after that I reboot my host OS(suse11sp3).
There is a same problem in KVM too.
2、problem:
I started a VM whose memory is 64G in the host.
The size of memory inside of the VM is wrong while it is OK when I check
it in the host using "xl list".
But, when I changed the memory to 63G,it was both OK.
(1)64G memory
inside of VM using "free" to check:
total used free shared buffers cached
Mem: 3715640 495916 3219724 0 22060 175136
-/+ buffers/cache: 298720 3416920
Swap: 4046840 0 4046840
It is only 3.5G.
in the host using "xl list" to check:
Name ID Mem VCPUs State
Time(s)
Domain-0 0 3055 16 r-----
861.2
redhat 4 65536 2 r-----
5.9
(2)63G memory
inside of VM using "free" to check:
total used free shared buffers cached
Mem: 64918224 1083912 63834312 0 22188 175344
-/+ buffers/cache: 886380 64031844
Swap: 4046840 0 4046840
It is OK.
in the host using "xl list" to check:
Name ID Mem VCPUs State
Time(s)
Domain-0 0 3055 16 r-----
821.2
redhat 3 64512 2 -b----
48.5
3、my cfg file:
builder = "hvm"
name = "redhat"
memory = 65536
maxmem = 65536
vcpus = 2
bios = "ovmf"
boot = "dc"
sdl=0
disk = [ 'file:/test/image/redhat6_3.img,xvda,w' ]
vnc = 1
vnclisten = '9.61.1.31'
vncdisplay = 0
Any thought on this?
Any help will be appreciated.
If you need some other information, please let me know. :)
Thanks!
