rhtyd opened a new issue #4112:
URL: https://github.com/apache/cloudstack/issues/4112
The systemvms are patching on KVM are currently performed patch.sh that uses
qemu-agent-command (a serial-device mechanism) and consumed in the systemvms
via qemu-guest-agent. Newer qemu versions (at least 2.2+) can make use of the
qemu fw cfg device to pass key/value strings for the `cmdline` without using a
more brittle/low-level approach much like XenServer and VMware, and inside the
systemvm they can consume the value for the `cmdline` at
`/sys/firmware/qemu_fw_cfg/by_name/...` path which is available in newer
kernels.
