Unable To Remove /cgroup/freezer/libvirt/qemu

DomU's interface hangs after short time under heavy network load (starting at ~10Mbyte/s). commit d89608f994025aef9809bcb224e2d71f35fb85e9 Author: Laine Stump Date: Sun Jan 23 16:02:42 2011 -0500 Add a function to the security driver API that sets the label of an open fd. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was located. If dynamic_ownership gets set back to 1, you will see a failure like this. http://mixtecadigital.com/unable-to/unable-to-remove-oci-dll.html

When i tried to delete the snapshot he doesnt appear in the least of snapshots. Network load testing has not caused failures. Dan B we made some changes to set the label on the socket for MLS mode, do you think this is related? In this case you are relabling a fifo_file, which I guess the kernel stores in some kind of file system.

I'm not sure what else I can do to help figure out what is going wrong, but please let me know if some other piece of information would be helpful.

We start receiving ARP only if we reboot the vm's. Note that the partition names in the guest XML are using a generic naming format, not the low level naming convention required by the underlying host OS. The legacy cgroups layout described later in this document did not support customization per guest. Reboot from the host is the only solution.

You may reopen this bug report if the solution does not work for you. The difference this time is that I can run a tcpdump -i eth0 and "wake up" the interface so it starts working again. None of them are compulsory. The virt-manager GUI reports the following stack-trace: Error starting domain: error from service: CreateMachine: File exists Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper callback(asyncjob, *args, **kwargs) File

One is to try fsetfilecon(pipe[1], "svirt_t:MCS") If this does not work. This report is therefore being closed with a resolution of ERRATA. https://www.centos.org/forums/viewtopic.php?f=14&t=45002 ~0019973 james.shirley (reporter) 2014-06-20 00:41 Hi guys, have you managed to fix this or know of a work around.. Comment 24 Laine Stump 2011-01-31 15:33:47 EST Note also that the original problem was related to the *save image* also being on the NFS share, not just the disk.

Details are in the patches sent to rhvirt-patches. Logging in to the domain as root and using the 'shutdown -h now' command, the domain halts (apparently normally).

There are 3 ways we found to fix this issue 1) Migrate to another host : after a migration to another hypervisor, we no longer have this problem. ...so chances are this contact form By default the init system (such as systemd) should mount all controllers compiled into the kernel at /sys/fs/cgroup/$CONTROLLER-NAME. I seem to have the same issue over here with two identical Centos 7 servers.

When you will reinstall, choose a different ip address, on another ip range where you don't see this issue. 3) If you cannot change the ip of a vps, and cannot Star 0 Fork 0 relrod/gist:1025424 Created Jun 14, 2011 Embed What would you like to do? Comment 15 Daniel Walsh 2011-01-24 10:55:34 EST No for this case only since SELinux seems to be putting this label on a file system. http://mixtecadigital.com/unable-to/unable-to-remove.html We had two eth, it only happen in one of them.

So it seems centos6.2 isn't compatible with kvm. ~0015361 bmalynovytch (reporter) 2012-07-03 06:44 It sounds like it is (was ?) due to a memory (leak ?) in the virtio-net driver. If we start to create or destroy the domain through virsh all we can get is this : error: Failed to create domain from /etc/libvirt/qemu/9099.xml error: Unable to create tap device http://rhn.redhat.com/errata/RHBA-2011-0596.html Note You need to log in before you can comment on or make changes to this bug.

In both cases, libvirtd opens a pipe, and passes one end of it to QEMU, so the labelling on that pipe wouldn't have changed. @dwalsh, the MLS socket stuff was labelling

Note: the ability to place guests in custom partitions is only available with libvirt >= 1.0.5, using the new cgroup layout. Reload to refresh your session. Acknowledgement sent to Paul Millar : Extra info received and forwarded to list. My feeling is that this thread consists of a mix of different issues.

Make sense? The QEMU driver is capable of using the cpuset, cpu, memory, blkio and devices controllers. Comment 7 Laine Stump 2011-01-20 13:10:21 EST Unfortunately, apparently it's not exec:cat vs. Check This Out Install: cgroup-lite:amd64 (1.1.5, automatic) We need to reboot the system each time this happen.

Once there is no longer any vps on the range, backup your config, delete the problematic range from your configuration and then re-configure the range in question using your previous settings. And some issue may be fixed with the patch provided. ~0017743 cstrom (reporter) 2013-07-31 00:01 We have the exact same problem described at btallent and mlorenzo.

Comment 6 Eric Blake 2011-01-20 11:44:18 EST My guess is that this is fallout from using the new '-incoming fd:n' which directly accesses the file from qemu, then qemu closes the
