Hello: I am wondering if KVM is ready for production for running a Windows Server 2003 32 bit guest. According to the RHEL 5.4 virtualization guide, there is supposed to be a virtio-win yum package, but that was not released. Instead, it looks like that is only available for RHN subscribers. Also, I saw this posting on the CentOS list: --- Quoted from CL Martinez There are freely

Hello: According to the Red Hat Virtualization Guide, Windows Server 2003 32-bit will only run as a fully virtualized guest on an AMD64 system.

Hello: I am looking for a recommendation for a PCI-e RAID card for my server. The server has a PCI-e x16 low profile slot so the card has to be at most 6.6 inches long x 2.536 inches high. I would like to use RAID 5 with 3 drives so I have to have those capabilities. It has to be CentOS 5.4 compatible (Of course!). I took a look at the offerings from 3Ware, but their cards are too long. If

Hello: I have a host running two KVM guests. The guests use br0 and each has a static IP address. I am trying to figure out if there is a way to use snmpd on the host to measure the traffic usage of the guests. I do not want to require anything running on the guests since I do not control them.

Hello: I am looking at the RHEL 5.4 virtualization guide. According to Chapter 17, if I want to use KVM on my machine, I need to check if it has the constant Time Stamp Counter by running this: cat /proc/cpuinfo | grep constant_tsc When I do that on the server (Currently running CentOS 5.3), I do not get any output. According to the output, that means my system does not have the counter. It
