Re: [CentOS-virt] VM Slowness
Is the one that is slow the one that has 2g resident? 2 Gigs ram? Yes. ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt
[CentOS-virt] VM Slowness
I hope this in the right list, but I was wondering if someone could help me with a VM I have that has lately started having problems. It had been running for years without problems. It's possible an update is causing this, but I can't say. The VM is running CentOS 5.8 and after a time, the machine begins to slow down. Things like pings or running commands lag. If I reboot the VM, it runs normally for at least a few hours, but it eventually slows again. I've tried changing the VM's virtio devices to standard devices like IDE and e1000, but it makes no difference. Currently its running virtio. Top shows that nothing is taking up significant cpu time, but even running top takes several seconds for it to open. The system is slow now, but top shows: top - 21:39:48 up 1 day, 5:27, 1 user, load average: 0.93, 1.37, 1.12 Tasks: 177 total, 1 running, 176 sleeping, 0 stopped, 0 zombie Cpu(s): 0.3%us, 0.3%sy, 0.0%ni, 98.6%id, 0.9%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 2075016k total, 1484624k used, 590392k free,64336k buffers Swap: 4128760k total, 12k used, 4128748k free, 981368k cached PID USER PR NI VIRT RES SHR S %CPU %MEMTIME+ COMMAND 4124 root 20 0 2444 1080 812 R 0.1 0.1 0:00.03 top 1 root 15 0 2176 692 604 S 0.0 0.0 0:02.46 init 2 root RT -5 000 S 0.0 0.0 0:00.39 migration/0 3 root 34 19 000 S 0.0 0.0 0:00.00 ksoftirqd/0 Any ideas what to look for?

Re: [CentOS-virt] VM Slowness
Did you try this vm on other host with diffrent virtualization system(Virtual Box, etc)? 20.05.2013, 07:55, "compdoc" comp...@hotrodpc.com:I hope this in the right list, but I was wondering if someone could help mewith a VM I have that has lately started having problems.
