Provisioning of "static" VMs for CI at potemkins
I was too lazy to install OpenStack, so I decided to use a bunch of
predefined VM almost-templates to provide build nodes which do not leak
that much state behind runs of independent jobs. It turns out that it's
still hard to provision a recent Fedora box with a rootfs overlay, so I
gave up on that. Qemu supports transient disks, but the changes are
stored in RAM, which sucks, IMHO.
Here's how to actually create the VMs:
virt-install --hvm -n ci-f29-potemkin06-1 --memory 62000 --cpu host-passthrough --vcpus 12 \
--location http://ftp.fi.muni.cz/pub/linux/fedora/linux/releases/29/Server/x86_64/os/ \
--initrd-inject ci-f29-potemkin06-1.ks --os-variant fedora26 --network network=ipv6-public \
--extra-args='ks=file:/ci-f29-potemkin06-1.ks console=ttyS0' \
--disk pool=ssd,size=10 --disk pool=ssd,size=50,cache=none --nographics --noautoconsole
This will also require changes within the base jobs to call a reboot via
Ansible within a job pre-run playbook. That should add just something
like 20s to any given run...
