Add an option to specify the number of MSI-X vectors for PCI NIC cards. This can also be used to disable MSI-X, for compatibility with old qemu. This option currently only affects virtio cards.

I'm running KVM on a standard Debian Lenny host, and I seem to be hitting the problem identified here: http://serverfault.com/questions/123566/is-anyone-using-kvm-in-production My symptom is that using rsync over SSH to transfer files into the guest gets slower and slower, and then grinds to a halt, and the machine becomes unreachable. It seems that I should be using the virtio driver,

Greetings KVM gurus, I am trying to understand a "use case" scenario for the "vlan=n" option and "name=name" for the "-net nic" and "-net tap" directives. I have done some search but I have not come up with anything that sheds any light on the above. <quote from kvm man> Network options: -net nic[,vlan=n][,macaddr=mac][,model=type]

Did not get any response in the CentOS Virt list. Posting in the CentOS General list hoping that some one here can provide clarification.

There was no release since virtio support was introduced, so a proper migration is not necessary.

Hi, We are using Zenoss to monitor a number of paravirt Linux hosts (using the xen net device), it appears that an snmp query to the paravirt hosts is reporting the interface speed as 10mbit - which is significantly lower than what it really is (the dom0 host has 1gbit networking). This causes the occasional spurious error from the monitoring tool as it notices that a host is using 75% of its

This is a problem I've had on and off under CentOS5 and CentOS6, with both xen and kvm. Currently, it happens consistently with kvm on 6.5, e.g. with every kernel update. I *think* it generally worked fine with the 6.4 kernels. There are 7 VMs running on a 6.5, x86_64, 8GB RAM host, each with 512MB RAM and using the e1000 NIC. I picked this specific NIC because the default does not allow

I need to support 3.9 for another while and thought I would set up a local repo with base and updates merged into one. How can I update repodata? I don't see createrepo in 3.9. --------------------------------------------------------------- This message and any attachments may contain Cypress (or its subsidiaries) confidential information.

All machines kickstarted here consistently have a swap partition with the wrong size. According to the RHEL5 manual: | To determine the size of the swap partition automatically, use the | --recommended option: | | swap --recommended | | The recommended maximum swap size for machines with less than 2GB of RAM is | twice the amount of RAM. For machines with 2GB or more, this recommendation |

One thing I have noticed on CentOS6 is that rsync via xinetd never works after a reboot. It always takes an additional, post-reboot service xinetd restart to get it going. That has been the same for all revisions up to and including 6.5, and I've seen it on more than just machine. While I don't see such a message on other problem machines, the latest reboot gave me a clue: Dec 9

Ok, I'm having a major brain hemorrhage or something. I just can't get mrtg setup on my box. I've done it before and it's not like it's brain surgery but there's a mental block or something that I just can't get around. All I want to do is have a nice, simple graph of the traffic on the box and the gateway in the standard day/week/month/year thing. I've got the

Hi all. I am having an issue and quite frankly would rather not spend the entire next two days learning the entire snmp program. I am hoping someone out there has used MRTG and SNMP to make it work. I have both installed. Single server, polling itself. Question 1- does snmpd have to run as a daemon, or only run once so I can get OID and MIBs from it? Question 2- does anyone know the command

Hi all, I've started playing with kvm on CentOS 5.5, with not much success so far. In a nutshell, I have the same problem as http://lists.centos.org/pipermail/centos-virt/2010-April/001854.html I followed the RHEL5 virtualization guide to set up a bridge interface br0, and then used virt-install (rather than virt-manager - I like automation) to set up the vm. It hangs at some point.

Which configuration or rc script is responsible for loading the kvm modules on CentOS 5.4/5.5? They interfere with vmware. --------------------------------------------------------------- This message and any attachments may contain Cypress (or its subsidiaries) confidential information.
