Re: [Xen-devel] Balloon down memory failed in x86 PAE mode when memory s
My xen version is Xen3.4.0, and i use el5u2 pvhvm to have test.
The memory size is 6114. "xm info" dose not show any change on
free_memory after command "xm mem-set domid 4096". It seems free_memory
will change after i set memory size less than 3083M, such as: free
memory will increase 1 after command "xm mem-set domid 3082".
The vm configure file is following:
name = "OVM_EL5U2_X86_PVHVM_4GB"
builder = "hvm"
memory = "6114"
disk = [
'file:/mnt/running_pool/OVM_EL5U2_X86_PVHVM_4GB/System.img,hda,w', ]
vif = [ 'type=netfront', ]
device_model = "/usr/lib/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
vnc=1
vncunused=1
vnclisten = '0.0.0.0'
timer_mode=0
apic=1
acpi=1
pae=1
vcpus=1
serial = "pty" # enable serial console
on_reboot = 'restart'
on_crash = 'restart'
Thanks

Hi
I implemented balloon in windows pv driver, it works normally on x86 and
x64 OS.
However, i hit problem to balloon down memory on x86 PAE mode VM when
it's memory
size is larger than 4G.
Furthermore, i tested linux PVHVM too. Balloon driver also failed to
take effect
at the same situation.
So, is there anything missed in windows or linux PV driver when
ballooning down
memory on x86 PAE VM(memory>4G)? or is there a limitation in Xen for PAE
mode?
Thanks
Annie.
