similar to: quick question on schedinfo

Hi techs, Could you please explain or refer me to documentation where I could find a description of global_quota schedinfo option. Someone told me that it could mean a cpu limitation in percents like: global_quota : 25000 (does it mean cpu limit % set to 25 ?) Is it true? What other parameters mean in below output? I didn't find any related documentation at libvirt.org. Could you help me

I have 2 VMs launched by : 'virsh create <xml file>' . Both VMs get 2 vcpus (out of total 2 cores of the host) I then try bias their cpu cycle quota by manipulating the cpu_shares ( virsh schedinfo --set cpu_shares=<value> vm1/2 ) so that VM1 will get 3 times the cpu cycles VM2 gets. (e.g : VM1 cpu_shares = 150 . VM2 cpu_shares = 50) . There are no other VMs defined or

Hi, How can I add ''schedinfo'' to the domU configuration? These parameters are default after reboot. -- Regards, Piotr Jasiukajtis | estibi | SCA OS0072 http://estseg.blogspot.com

Hi, I'm running into some problems with libvirt and hoping someone can point me at some instructions or maybe even help me out. First, are there any requirements on qemu version in order to use the "numatune" and/or "cpu/numa/cell" elements? Or do they use cgroups and not the native qemu numa support? Second, are there any instructions on how to set up cgroups? I

Hi I tried to restrict usage of some running VM by cpu.shares (i.e. set to 10 from original 1024) on loaded system and it seem doesn't work as I expected... all running processes has same CPU usage (by htop) :-/ Does anyone has same experience?

Dear guys; I have a streamer; Pioneer N-50 which supports FLAC files. All my classical library is in FLAC and I have a problem when I play it through most of the media players and my streamer is that most of the CDs tracks are not played in order as if you are using shuffle to play them!!! If I convert the files to WAV this problem is solved, but I can't change my library to WAV because of

Hello, I have another question about cgroup in libvirt I create a script that put vm in cgroup for limiting blkio sudo cgcreate -f 750 -d 750 -a $user:$group -g blkio:$alias pid=`pgrep $alias` echo $pid > /dev/cgroup/blkio/$alias/tasks $virsh schedinfo --set cpu_shares=$cpu $alias echo "8:0 $disk_io" > /dev/cgroup/blkio/$alias/blkio.throttle.read_bps_device echo "8:0

Hi, I'm using libvirt/kvm with openstack. When vm has CPU stall, the instance can't be destroyed. I have asked the question on openstack user mailing list and received no answers in weeks. Here is one example: # virsh destroy instance-00000085 error: Failed to destroy domain instance-00000085 error: Failed to terminate process 61222 with SIGKILL: Device or resource busy

Hello, First of all, happy new year! I am interested in the hot plugging facilities of libvirt, in particular in what qemu calls 'hot add' of network interface cards. (And also the reverse: hot unplugging/removing of NICs.) I think I am overlooking something, but so far the best I have been able to find is: http://libvirt.org/sources/virshcmdref/html/ and it is not entirely clear

Hi, Look under examples: http://builder.virt-tools.org/artifacts/libvirt-virshcmdref/html/sect-attach-disk.html (root at h2)-(/)# virsh attach-disk vps_99 /dev/nbd2 vdb --address pci:0000.00.11.0 --persistent *error: command 'attach-disk' doesn't support option --address* (root at h2)-(/)# virsh --version 0.7.5 Is someone playing a trick on me?

I am wondering what the default value for migrate-setmaxdowntime is when using QEMU/KVM. http://builder.virt-tools.org/artifacts/libvirt-virshcmdref/html/sect-migrate-setmaxdowntime.html Is the default the same as QEMU's default in this case? I was looking at libvirts source and it appears there is no default set within libvirt, unless I missed it. I do see

Hi, I have downloaded libvirt-0.9.11 and compiled it on my RHEL 6.2 system. I am trying to build a binary RPM for distribution, I am not sure what the best way to go about doing this is. http://libvirt.org/FAQ.html suggests that I try 'make rpm', however that ends in the below error: missing XHTML1 DTD cp: cannot stat `./api.html': No such file or directory make[2]: *** [distdir]

Hi list, According to the libvirt documentation [1] "Show maximum number of virtual CPUs for guest domains on this connection" This may not be a complete definition. My first guess from the above was that this returns the number of virtual CPUs that can exist at the same time on the host, either one or several VMs. In fact it returned 16 in my fedora 20 desktop running with KVM,

We use Informix database. I was able to connect to the database with S-PLUS by using its CONNECT/Java through the JDBC driver. How can I connect to Informix with R, wither using JDBC or any other method? we run Linux so I prefer a method other than ODBC. Thankx for the help
