Bug 622955

I have Fedora 13 x86_64 on an Athlon II x2 CPU.
4GB ram, and a 500GB hard disk dedicate as VM storage via LVM.

I have a script to create CentOS 5.5 VM's using HTTP install and kickstart, using the Host as the HTTP server.

$NAME is passed to the script.

virt-install --connect qemu:///system \
	--wait 10 \
	--os-variant=rhel5.4 \
	--os-type=linux \
	--name $NAME \
	--ram 256 \
	--vcpus=1 \
	--disk path=/dev/KVM_Volume/$NAME,bus=virtio \
	--network bridge=br0 \
	--noautoconsole \
	--location http://192.168.1.251/centos/5.5/os/x86_64/ \
	-x "ks=http://192.168.1.251/centos/kickstart/centos-base.ks"


I loop through this script 10 times:

# for i in $(seq -w -s " " 1 10); do lvcreate -n VM_$i -L 10G /dev/KVM_Volume; ./centos-vm.sh VM_$i; done;

Periodically, a virt-install may fail:
