Those threads do not cause any problems, the host is dealing with a lot of them and has no problem (CPU usage and load is incredibly low in practice). Thank you for the clarification, I see why are there more threads

Hello guys! We want to move some guests' disk images to different locations (within the same machine, locally), but we do not want to turn off the guests. Can we do that while the guest is running, like live migration? I did not find any related documentation or posts about it. Let's say the guest has a disk at /ssd/image.raw We want to move that to /hdd/image.raw Is there any way to

What does this mean? Will I loose anything if - for example - there is not enough space on

Hello guys! We have a lot of virtual machines and I recently tried out the migrate feature of libvirt. It works like a charm, even without shared storage, but when we try to migrate a VM under a little pressure (a HTTP server gets some 1-5 requests/sec) the migration process hangs at 99%. After we stop the stressing of the VM, the migration immediately finishes. I'm using the following

Dear all, I'm running GlusterFS 3.4 alpha2 together with oVirt 3.2. This is solely a test system and it doesn't have much data or anything important in it. Currently it has only 2 VM's running and disk usage is around 15 GB. I have been trying to set up a geo-replication for disaster recovery testing. For geo-replication I did following: All machines are running CentOS 6.4 and using

Hi guys. These days I'm doing research on SR-IOV & Live migration. As we all know there is big problem that SR-IOV & Live migration can not exist at the same time. I heard that KVM + SRIOV + MacVtap can solve this problem. So I want to try. My environment: Host: Dell R610, OS: RHEL 6.4 ( kernel 2.6.32) NIC: intel 82599

Hi there, some of my users use putty to connect to my server via ssh protocol. After some time they get the above error message, and it could be that my CentOS-side configuration caused this. Do anybody has experience with this problem? - Gergely

Hi! LLVM newbie here, I was mainly working on the frontend so far. We had a small hackathon project idea to piggyback on LTO to detect dead code (unused functions). The basic idea is to compile the code for every target and dump the removed functions. Intersect the function symbol names for each target and those functions should be safe to remove from the source code (unless there were some

Hi! Why not automagically delete generated header files like this? File.open("Makefile","ab+"){|f| f.puts f.puts("tclean:; @$(RM) "+(Dir[''*.t''].map{|fn| fn.sub(''.t'',''.h'')}.join)) f.puts } Reduces user error :) Gergo -- +-[ Kontra, Gergely<kgergely@mcl.hu> PhD student Room IB113 ]---------+ |

Hello, I've got a very strange problem. Lately I've been setting up my linux servers for network (layer2) redundancy with a bridge interface containing two ethernet interfaces connecting to two switches. So far I didn't have any problems with it, but now a very strange thing happens with a new server I'm installing. The server is an ibm x346 having two onboard BCM5721 cards, the

_netdev The filesystem resides on a device that requires network access (used to prevent the system from attempting to mount these filesystems until the network has been enabled on the system). This device is not a network device (this a SAN not a NAS). To the OS it looks like a normal SCSI attached device, it's /dev/sdb. In the blade there is a HBA (Qlogic) card, and it's
