I built rc2 and used the pvops kernel pulled from git for dom0 (make linux-2.6-pvops-build). dom0 runs much slower than the the vanilla kernel (without xen), and the system as a whole, including the domUs I''m running, seems sluggish. More of a concern is that I''m getting random segfaults in the domUs. I have 2 domUs running: one using the 2.6.18-xen (built for 3.4.2), and another using kernel.org 2.6.32.7. I can''t be sure it''s not a hardware problem (as I''ve also upgraded my MB) but both the RAM (tested with Memtest86) and the HD (tested with the WD diagnostic tool) seem ok. Here''s a sample of the domU segfaults (I can''t reproduce them - they''re random): gnome-panel[3232]: segfault at 7f5264a27390 ip 00007f5263a8205d sp 00007fff74ce9630 error 4 in libc-2.10.2.so[7f5263a11000+14a000] sshd[6373]: segfault at 000000ffadffd8ff rip 000000ffadffd8ff rsp 00007fffb61abab8 error 14 At one point I was using the dom0 kernel for one of the domUs and that crashed a few times, so I switched to kernel.org''s 2.6.32.7 The domU using 2.6.18-xen has always been rock-solid before under 3.4.2 and earlier (it uses Debian Stable). Let me know if you want log/config files. Thanks, Yasir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Is your kernel.org 2.6.32.7 kernel 32bit? If yes, do you have CONFIG_HIGHPTE=y in .config? -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Hi Pasi, All the kernels are 64-bit.
