The previous dmesg was captured during about 10 hr day. Stack traces were cumulated at the end one by one ( about 6-9 similar entries). Now i rebooted the box. Started Virt-Manager and F13 guest . Then begun rotate cube ( desktop)

.config from Ubuntu instance just copied over to F13 instance.  2.6.32.19 rebuilt on F13 with minimal initramfs and get 3D on F13.   I also made diff between .configs   Looks like CONFIG_DRM_RADEON=y caused a problem   should be =m.   CONFIG_DRM_RADEON_KMS=y to make modesetting on radeon by   default.  Boris. --- On Wed, 8/18/10, Boris Derzhavets <bderzhavets@yahoo.com> wrote: From:

Previous 2.6.31-rc8 kernel was built on F11 and installed with modules on F12. Current kernel has been built on F12 (2.6.31-0.204.rc9.fc12.x86_64) and installed on F12 before loading under Xen 3.4.1. Dmesg log looks similar to Michael Yuong''s ''rc7.git4''  kernel for F12. Boris. --- On Tue, 9/8/09, Boris Derzhavets <bderzhavets@yahoo.com> wrote: From: Boris

I've tried with KSM disabled and nothing changed. I've upgraded KVM to qemu-kvm-ev. I'm waiting to see if there are any improvements and report back. ?n mie., 17 aug. 2016 la 15:10, Boris Derzhavets <bderzhavets at hotmail.com> a scris: > For myself KSM is unpredictable feature.

  Tne answer is NO. Any vanilla kernel (> 2.6.27) itself allows only to enable PV Guest (paravirtual) mode, but not Xen Dom0 Support. Mainline Linux doesn''t  contain Xen Dom0 Support merged. You have to work on it on your own.   I''ve sent you two links in the very first message. View second one - patching 2.6.30.1 via Andrew''s Lyon rebase patch set :-  

Both baremetal and compute ? Are there any other metrics do you consider useful to collect for troubleshooting purposes ? ?n mie., 17 aug. 2016 la 13:04, Boris Derzhavets <bderzhavets at hotmail.com> a scris: > It sounds weird, but attempt to disable KSM and see would it help or no ? > > > ------------------------------ > *From:* centos-virt-bounces at centos.org

It is rc2-pre.

For myself KSM is unpredictable feature. The problem is Compute, just this node does "copy on write" , so only Compute. My concern exactly is where would it lead to worse or better Guest behavior ? I am not expecting complete fix. I would track via top/htop and dmesg via Cron on 1-2 hr period. ________________________________ From: centos-virt-bounces at centos.org

Enabled the logging on both compute and baremetal.

It sounds weird, but attempt to disable KSM and see would it help or no ? ________________________________ From: centos-virt-bounces at centos.org <centos-virt-bounces at centos.org> on behalf of Laurentiu Soica <laurentiu at soica.ro> Sent: Wednesday, August 17, 2016 4:56 AM To: Discussion about the virtualization on CentOS Subject: Re: [CentOS-virt] Nested KVM issue Enabled the

Yes.

Yes. First remove old :- # rm -fr xen-3.4-testing.hg # hg clone http://xenbits.xensource.com/xen-3.4-testing.hg It takes 20-30 min at 100Kb/sec ADSL connection. # cd xen-3.4-testing.hg # make world. You always run "make world" UNDER xen-3.4-tesing.hg  folder,  NOT under /usr/src. Do it step by step. Boris. --- On Wed, 6/17/09, Jan Muhammad <janmuhd@yahoo.com> wrote: From:

No luck with qemu-kvm-ev, the behavior is the same. Running perf record -a -g on the baremetal shows that most of the CPU time is in _raw_spin_lock Children Self Command Shared Object Symbol - 93.62% 93.62% qemu-kvm [kernel.kallsyms] [k] _raw_spin_lock - _raw_spin_lock + 45.30%

I have installed Ubuntu Intrepid Server on bare metal and successfully ran:- # apt-get install ubuntu-xen-server.     It installed several packages on system . Now i can see files /boot/xen-3.3.gz, /etc/init.d/xend, /etc/init.d/xendomains, but no xenified kernel gets in. Attempt  to use vmlinuz-2.6.27-7-server, obviously , fails with system panic.    I do remember recompiling  procedure for Xen
