So I run this command with vmbuilder without tmpfs since I want this machine persistent.
vmbuilder kvm ubuntu --suite=lucid --flavour=virtual --arch=amd64 --mirror= http://192.168.1.4/ubuntu -o --libvirt=qemu:///system --ip=192.168.1.50 --gw=192.168.1.1 --part vmbuilder.partition --user=user --name=user --pass=pass --addpkg=wget --addpkg=cron --addpkg=vim --addpkg=ntp --addpkg=ntpdate --addpkg=ssh --addpkg=xvfb --addpkg=build-essential --addpkg=linux-headers-virtual --addpkg=locate --addpkg=postfix --addpkg=vpnc --addpkg=acpid --addpkg=clamav --addpkg=chkrootkit --addpkg=rkhunter --addpkg=apache2 --addpkg=openssl --mem=512 --hostname=vm00 --bridge=br0 I start the vm and it runs fine: Then I start another vm that I want to do testing on with tmpfs: vmbuilder kvm ubuntu --suite=lucid --flavour=virtual --arch=amd64 --mirror= http://192.168.1.4/ubuntu -o --libvirt=qemu:///system --tmpfs=- --ip=192.168.1.51 --gw=192.168.1.1 --part vmbuilder.partition --user=user --name=user --pass=pass --addpkg=wget --addpkg=cron --addpkg=vim --addpkg=ntp --addpkg=ntpdate --addpkg=ssh --addpkg=xvfb --addpkg=build-essential --addpkg=linux-headers-virtual --addpkg=locate --addpkg=postfix --addpkg=vpnc --addpkg=acpid --addpkg=clamav --addpkg=chkrootkit --addpkg=rkhunter --mem=512 --hostname=vm01 --bridge=br0 I start the vm and it runs fine as well. I then do a reboot on the actual server running both virtual machines. When the server comes backup vm01 is running and vm00 is not. Then when I try to start vm00 I get: Id Name State ---------------------------------- 1 vm01 running - vm00 shut off virsh # start vm00 error: Failed to start domain vm00 error: monitor socket did not show up.: Connection refused Maybe I'm missing something trivial.
