Regarding Perfctr-Xen (see announcement below), some have requested author''s version of the published paper. It is available on my website: http://people.cs.vt.edu/~rnikola/?page_id=159 Please, let me know what you think. Also, I want to iterate my point regarding Perfctr-Xen vs XenoProf: XenoProf is useful but has a number of limitations such as system-wide monitoring only.

I've tracked down the issue to the seabios package being updated to 1.7.4-1 from 1.7.3-3. When Xen is built with the older version, everything works fine. In fact, I bisected the issue down to the following SeaBIOS commit: http://review.coreboot.org/gitweb?p=seabios.git;a=commit;h=e144bb7af49ca8756b7222a75811f3b85b0bc1f5 I don't know if this group is interested in tracking down the

When using the 4.3.0-3/4.3.0-3+b1 xen packages from the Debian archive, things work fine. However, when we compile the xen=4.3.0-3 source package ourselves, we run into an issue launching an HVM. As soon as the HVM bios is loaded, VCPU0 gets a triple fault and the HVM is destroyed (this is with "loglvl=all guest_loglvl=all hvm_debug=3" boot options). (XEN) HVM1: Multiprocessor

Has anyone succesfully compiled a PAPI+perfctr-enabled kernel? I've been mixing and matching instructions from the PAPI distribution and those from CentOS wiki to no avail. TIA -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina

Hi all: We have a user who needs to do some work with PAPI, which requires the perfctr patch applied to the kernel proper. Before I do that work here, I wanted to ask the list if anyone knows of a repo where such kernels are available? Also, if anyone has gone down this route and has helpful hints, perspectives, horror stories, etc., I would covet that information also. Cheers and Thanks,

Hi, I had a C7 virtual machine running on a C7 host for several weeks without any problems. Today I rebootet the host and now the virtual machine does not start anymore. I can see grub coming up and starting the kernel. After some seconds the last thing that is visble on the VM console is "ss perfctr msr (MSR c1 is0)" then the screen goes blank with just a blinking cursor in the upper

Hi, i'm rather new to kvm. now i set up a centos 7 guest on a centos 6 kvm host. when i try to use bridged networking in the centos7 guest this works for the interface that uses eth1/br1 on the host. when i try to use a second interface in the guest with eth0/br0 on the host this brings the host interface down as soon as i do ip configuration in the guest (so it seems). eth0 shall have

Hi keir, In credit scheduler, two vcpus in the same domain may be scheduled on the same CPU. For instance, vcpu0 and vcpu1 are running on the same CPU, vcpu0 is doing spin_lock in guest, then time slice is due, vcpu0 is scheduled out before doing

Hi, As told in "Control Groups Resource Management" libvirt page : Legacy cgroups layout Prior to libvirt 1.0.5, the cgroups layout created by libvirt was different from that described above, and did not allow for administrator customization. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was
