[Users] Cannot stop or restart container
Hey guys. I reported a bug some months ago, not being able to stop and restart a container, getting a timeout instead. When I reported the bug months ago, I was unable to replicate it at the time. But here it is once again: I cannot stop or restart the VE. This clip shows the results which I see: # vzctl restart Customer Restarting container Stopping container ... Unable to stop container: operation timed out # vzlist Customer CTID NPROC STATUS IP_ADDR HOSTNAME 84 3 running - Customer The 3 processes, I don't know what they are but they may be related to this, and may be a clue: After the initial vzctl restart, it got down to 1 process before it timed out. I ran vzctl exec Customer ps ax and now I notice that the NPROC increments each time I do this. However from the HN, ps ax | grep ps only shows the one 'ps' which I am running, not the ones in the VE. Any thoughts on how I can finally stop this thing and restart it? Note that this is a production HN with production VEs, so rebooting it is not an attractive option.

Re: [Users] Cannot stop or restart container
I recently had a similar result from an Archlinux template, however I would need to know more about the container to be able to relate it to my case. Can you vzctl enter it? I have a restart problem on a self made gentoo container however I know the cause. It gets locked up trying to stop nfsmount. I believe the problem is the virtual nic is down before the nfsmount tries to stop and nfsmount waits forever to close the connection to the server..

Hi, and any entries logged in kern.log/dmesg as well ? Bye, Thorsten Steven Crothers schrieb: What template are you using and where did you get it from?

Re: [Users] Cannot stop or restart container
It gets locked up trying to stop nfsmount. I believe the problem is the virtual nic is down before the nfsmount tries to stop and nfsmount waits forever to close the connection to the server.. Interesting. No connections made here, though; no NFS or similar. Would that apply to open listening sockets as well, e.g. httpd still running? -- HostGIS, Open Source solutions for the global GIS community Greg Allensworth - SysAdmin, Programmer, GIS Person, Security Network+ Server+ A+ Security+ Linux+ PHP PostgreSQL MySQL DHTML/JavaScript/AJAX No one cares if you can back up — only if you can recover. ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users

BTW, if you open a second terminal and vzctl enter you can see what's going on. That is how I determined the cause of my problem..

[Users] Cannot start container, error -12
What does this mean? CT: 85: failed to start with err=-12 I see that -12 is ENOMEM. Does this really indicate that my HN is full and can't run anymore VEs? Also, can someone explain to me the proper usage of vzmemcheck and how to interpret its output? -- HostGIS, Open Source solutions for the global GIS community Greg Allensworth - SysAdmin, Programmer, GIS Person, Security Network+ Server+ A+ Security+ Linux+ PHP PostgreSQL MySQL DHTML/JavaScript/AJAX No one cares if you can back up — only if you can recover. ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
[Users] libvirt progress
Is there anyone on this list that can update me on the progress of libvirt integration with openvz? With the latest libvirt I am able to start and stop a domain that is defined with a openvz config file, but I have not yet been able to migrate to full libvirt control As an example migration does not seam to work at all. Any help would be greatly appreciated, in fact, we are willing to pay to get this fixed.

Perhaps this question is better suited to the libvirt list?

I have actually, the problem is libvirt already supports all of this, the issue is on the interfacing with OpenVZ side of things just like with Xen and KVM. -Original Message- From: users-boun...@openvz.org [mailto:users-boun...@openvz.org] On Behalf Of Nathan Stratton Sent: Tuesday, March 30, 2010 9:41 PM To: users@openvz.org Subject: [Users] libvirt progress Is there anyone on this list that can update me on the progress of libvirt integration with openvz?
