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. I thought I have seen a lot of discussion about running paravirtualized Windows on CentOS. Is that a bad idea?

Hello: I am trying to follow the RHEL virtualization guide to set up a bridge on a system running CentOS 5.4. I copied my ifcfg-eth0 to ifcfg-eth0:1 and set its content to this: DEVICE=eth0:1 HWADDR=[The MAC address from eth0] ONBOOT=yes BRIDGE=br1 I then created ifcfg-br1 with this content: DEVICE=br1 TYPE=Bridge BOOTPROTO=static BROADCAST=192.168.2.255 IPADDR=192.168.2.202

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. Looking at netstat -in on the host, I see this info: Kernel Interface table Iface MTU Met

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

Hello: I have been looking into projects that will automatically restrict hacking attempts on my servers running CentOS 5. I think the two top contenders are: DenyHosts - http://denyhosts.sourceforge.net Fail2ban - http://www.fail2ban.org >From what I see, DenyHosts only blocks based on failed SSH attempts whereas Fail2ban blocks failed attempts for other access as well. The main benefit

Hello all: I am trying to install CentOS 5.4 as a KVM guest. The host is running CentOS 5.4 and does not have X installed. I used ssh to connect to the host and ran this command (I formatted it for readability, it is all on one line): virt-install -n jamm12e -r 1024 --vcpus=1 --check-cpu --os-type=linux --os-variant=rhel5 --hvm --accelerate --cdrom=/tmp/CentOS-5.4-x86_64-netinstall.iso

Hello all: I am trying to follow the RHEL virtualization guide. According to Chapter 17, I have a processor without a constant Time Stamp Counter (Its an Opteron).

Hello all: Is there a network switch that will give me traffic stats at an IP address level? Right now, I only get statstics at a port level, but that does not help since each of my servers run several virtual machines and I need to measure traffic per virtual machine.

Hello: I have a Supermicro SuperServer 5015P-TR. It has a Pentium D and is running CentOS x86_64. Can this machine use 8GB RAM? I think it should because it is running a 64 bit OS, but I am concerned because it is fundamentally 32 bit hardware. Anyone have any experience in this area?
