Hi I am trying to do passthrough to guest using sriov and libvirt I tried to use both techniques from here http://wiki.libvirt.org/page/Networking#Assignment_with_.3Chostdev.3E <http://wiki.libvirt.org/page/Networking#Assignment_with_.3Chostdev.3E> Assignment from a pool of SRIOV VFs in a libvirt <network> definition Assignment with <interface

I can see from different post that if working with sr-iov, i should work with vlan Is this an obligation to work with vlan if working with sr-iov? If not according to which parameter will the different vf get the traffic. Let's say i declare max_vfs=7, how will the traffic be seperated between the vm? However till i get an answer i tried to work with vlan And i still don't get

I've a the following happen a couple times now, and my internet searches are failing to locate an answer to the problem. We've got a few servers that primarily house VMs using KVM. They've got E-3 cpus and 32 GB RAM, and they run stock CentOS 6.4, fully patched (not yet migrated to 6.5). The VM disk images are housed on an NFS server. None of the VMs is particularly

Hi all, I have installed a CentOS-8 server to accomplish some tests using kvm guests ? All these guests are centos8 also. When these guests starts, I always see errors like: [ 589.687915] kvm [2133]: vcpu0, guest rIP: 0xffffffff81a5bc98 disabled perfctr wrmsr: 0xc2 data 0xffff [ 596.210773] kvm [2201]: vcpu0, guest rIP: 0xffffffffb885bc98 disabled perfctr wrmsr: 0xc2 data 0xffff Is this a

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.

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

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,

This is likely (almost certainly) a hardware issue. However, I would like any guidance available on diagnosing the exact cause and remedy. We have a warm standby server then went off line over the weekend. The problem manifests itself as a kernel panic during the centos boot process. The issue appears to be with auto-mounting a number of pci devices. Unfortunately the error messages scroll

Dear Rusers, I'd like to take the cases of cancer of the larynx in chorley(spatstat) to explain my question. I want to join the points of cancer of the larynx with the disused industrial incinerator to generate lines, and then calculate the angles of these line comparing the horizontal line? How can i get it? It seems to be difficult to get the angles Thanks a lot. -- With Kind

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

Having jotted down some models, with some inheritence I tried to run some unit tests. After waiting for rake test_units to run I got a rake of errors (if you''ll forgive the play on words). The errors were to do with unknown tables in the tear down stage. The unknown tables corresponded to sub-types where single table inheritence was used. In other words, these tables *shouldn''t*

Hello All, I don't have any reason to believe CENTOS (5.4) is underlying my difficulties but it's what I've got to work with so here's the setup: I have a 2P motherboard with 2 Opteron 2376s and two ethernet ports. The setup is fully virtualized, with Dom0, dom4 and Dom1 up and running. dom4 is attached to a dhcp service on eth0 and has no problems. I've recently
