Re: [CentOS-virt] disk io in guests causes soft lockups in guests and host processes

What helped a lot for me is to increase the read ahead drastically on guests: # Set read-ahead for optimal disk I/O blockdev --setra 16384 /dev/vda I optained this value by repeatedly timing copies and this was, for my installation at least, optimal.

Re: [CentOS-virt] Hey

I've used both Xen and KVM and at least in benchmarks of applications I did here I didn't see much difference and since KVM is natively supported by RedHat, that's what I've been using. Obviously on this list there is mostly Xen users, and I feel like I must be missing some great

[CentOS-virt] Traffic Accounting KVM vs Xen

We've been using CentOS 6.4 for both host and KVM guests for our own internal uses here, ftp server, mail servers, web server, etc. I am getting to where we want to offer virtual servers for lease but to do so we need some method of measuring and/or limiting traffic to individual

[CentOS-virt] Ethernet Not Talking

After applying a number of updates to both the host and the virtual machines, I had one virtual machine which would not talk to the network after the updates. Rebooting numerous times didn't help, I couldn't see anything wrong with either it's configuration or the bridge on the host

Re: [CentOS-virt] Very odd mouse issue

I've run into the same issue, screwing around with CONTROL-ALT-L, which is supposed to get you out of the window not in it, restarting the virtual manager, etc, eventually something seems to snap and it works, but I've not been able to determine either why it messes up or what corrects it.

[CentOS-virt] Windows Direct-X and Virtualization

Is there anyway to run a Windows machine as a virtual machine and have direct-X display on the host console in full screen mode? If anyone has this working can you tell me what hardware, drivers, etc you are using? Thank you.

[CentOS-virt] Time

Friday, I moved our servers to a new co-lo facility and ran into an interesting problem with virtual machines. I did an orderly shutdown of the CentOS 6.3 host, and it in turn suspends all the guests. It took about an hour and a half to move and fire up the host. The guests,

Re: [CentOS-virt] Time

I thank everyone for their input. I prefer to have the guests suspend rather than shutdown because many of my customers start things up manually and get annoyed when they come back to find them not running. Most of the time it is for a simple reboot of the host to make a new kernel or some

Re: [CentOS-virt] (no subject)

About the only thing you can do is not run Windows, or at least that version, XP does the same thing, continuouslys spins the CPU when there aren't any user processes using time. I've heard this is resolved in Windows-7 but haven't tried it personally.
