similar to: Errors while using blkiotune command

Hi, Hu Tao I noticed that in your patch about blkiotune.device_weight, You set the device blkio weight value between 100 and 1000. But from the kernel document, I see that the blkio weight can be set from 10 to 1000. Why do you limit the weight minimum to 100 rather than 10 ? Looking forward your explanation, thanks! -------------- Best regards! GuanQiang 2013-01-18

Hi all, I am working with libvirt and I am trying to set cpu affinity. Now I can always use      virsh vcpupin <domain_name> <vcpu> <pcpu> to pin vcpus to pcpus. I want to do it using Python API. Now, there is function pinVcpu which is supposed to do that. But this is not working. For example I gave      dom.pinVcpu(0,1) but still my vcpu affinity is for all the pcpus. The

Hi all, I'm trying to restrict privileges of root user inside the container. I searched about it and got to know about "idmap" element in domain XML. I added "idmap" element in my container's XML file: <idmap> <uid start='0' target='1000' count='10'/> <gid start='0' target='1000' count='10'/>

I checked the capabilities. I do not know why the guest is only for vbox. <guest> <os_type>hvm</os_type> <arch name='i686'> <wordsize>32</wordsize> <domain type='vbox'> </domain> </arch> </guest> I want it run qemu-kvm. and when i run virsh define /etc/libvirt/qemu/demo.xml. It shows error:

Hi Gao, I checked the output of "lxc-checkconfig" command and it showed --- Namespaces --- Namespaces: enabled Utsname namespace: enabled Ipc namespace: enabled Pid namespace: enabled *User namespace: missing* Network namespace: enabled Multiple /dev/pts instances: enabled Here it shows that User namespace support is missing. I tried to check for Namespaces Support in kernel

Hi Gao, I appreciate your quick reply. >you can try create a file in container, and on host, the owner of this file is uid=1000. >and on the other side, if a file's owner is uid 1000 on host. in this container, you will >see the owner of this file is uid 0. I tried creating a file inside the container with root user. When I checked uid of the file on the host, it still gives me uid

Hi, is there a way to configure blkio via libvirt (xml)? Regards Erkan -- ?ber den grenzen mu? die freiheit wohl wolkenlos sein

Hello! We are using oVirt in our infrastructure, which uses libvirt as backend. Last time we needed to activate storage QoS aka libvirt blkiotune parameters. So some questions appeared about how libvirt limitation mechanism works: 1. What happened to overlimit storage traffic in small time period after we apply blkiotune parameters on high loaded virtual machine on fly: a) All over-limit

Hi all, I'm new to LXC and libvirt. I have created a LXC container using libvirt. In domain XML file I have mentioned "memory" and "current memory" as 256 MB. Now I want to check the memory inside the container, but whenever I run top command or try to cat /proc/meminfo, it shows host machine's memory which is 3GB. So is there any command by which I can check

I'm running libvirt 0.10.2 and qemu-kvm-1.2.0, both compiled from source, on CentOS 6. I've got a working blkio cgroup hierarchy which I'm attaching guests to using the following XML guest configs: VM1 (foreground): <cputune> <shares>2048</shares> </cputune> <blkiotune> <weight>1000</weight> </blkiotune>

Thanks Sanjay. Interestingly for me, disable-llvm-optmzns did not make a difference in the way the shift was handled. Does the initial IR generated for you show this difference when the option is passed?

Hi All, As the problem faced by many other folks that rails 2.3.2 is not working with cgi, Now I want to revert to rails 2.2.2 on my shared host (bluehost ) can anybody guide me how to revert to 2.2.2. I tried the following: 1. I installed the older rails gem "gem install rails --version 2.2.2 --include-dependencies " 2. I tried to set the PATH env to my rails 2.2.2 version and also

The regression for the reported case should be avoided after: https://reviews.llvm.org/rL297232 https://reviews.llvm.org/rL297242 https://reviews.llvm.org/rL297280 It would still be good to understand if the clang change was intentional or if that was a side effect that can be limited.
