hey all, I have managed to compile my own versions of kernels from kernel.org. All goes well and the domU''s can boot fine. My issue is that I''m unable to get the domU to display the correct memory. An example. Kernel 2.6.32.7 shows 497MB of ram. Same amount confirmed when i cat /proc/meminfo. The vm .cfg file says 512. xm list show 512 as well. Kernel 2.6.31.12 shows 522 of ram. Same amount confirmed when i cat /proc/meminfo. The vm .cfg file says 512. xm list show 512 as well. Did I miss something in my kernel compile? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

[Xen-users] RE: DomU not reporting correct ram size
to add to this... I think the issue is with xen-balloon driver and the newer kernels. I say this for when I compile the kernels without xen-balloon driver I get domU reporting memory of 497. When I compile with xen-ballon I get 522. I have tested this on several domU''s across several distro''s. Does anyone have any idea? ________________________________ From: xen-users-bounces@lists.xensource.com [xen-users-bounces@lists.xensource.com] On Behalf Of Robbie A.

Would I still need to apply the xen patches? I thought i read some where on xen.org that it''s no longer necessary to apply the xen patches for domU guests. ________________________________ From: Robbie A.

THanks for that. could the issue here be that we are running xen dom0 on 2.6.18 and trying to run 2.6.3x as domU? ________________________________ From: Fajar A.

RE: [Xen-users] RE: DomU not reporting correct ram size
with the kernels from kernel.org, i see that it has the ability to do Xen if you compile. Would I still need to use the xen.gz in my grub config? or boot the kernel directly? ________________________________ From: xen-users-bounces@lists.xensource.com [xen-users-bounces@lists.xensource.com] On Behalf Of Robbie A.

RE: [Xen-users] RE: DomU not reporting correct ram size
Hello, I have updated the machine to be running kernel version 2.6.27.5. Host machine is debian, domU is Fedora release 10 (Cambridge) provided by stacklit http://stacklet.com/downloads/images/list/Fedora In the xen config file, I have memory = ''512'' set. When I login to the DomU and issue free -m, it shows 522mb of total ram. What else can I try here? ________________________________ From: Fajar A.
