Re: [libvirt-users] [Solved] Error installing VM: "Process exited while reading console log output"

Yeah, I'm trying to set up virtual machines in an old host system, which I plan to reinstall – likely with a newer OS version – after I move all of its services to the VMs. :) I installed backported packages of libvirt 0.9.12 and qemu-kvm 1.1.2. Running virt-install again failed, but this time QEMU gave a rather helpful error message: Starting install... Retrieving file MANIFEST... | 3.3 kB 00:00 ...

Apparently I misunderstood the units of the --ram option value… On my system which has 2 GiB of RAM, running virt-install with a --ram option value of "128" (128 MiB) instead of "$((128 * 1024 * 1024))" (128 TiB!) worked much better. :) So this is just a case of user error, hidden by a lack of output in an old version of QEMU.
