# Keepalive protocol:
# This allows qemu driver to detect broken connections to remote
# libvirtd during peer-to-peer migration. A keepalive message is
# sent to the daemon after keepalive_interval seconds of inactivity
# to check if the daemon is still responding; keepalive_count is a
# maximum number of keepalive messages that are allowed to be sent
# to the daemon without getting any response before the connection
# is considered broken. In other words, the connection is
# automatically closed approximately after
# keepalive_interval * (keepalive_count + 1) seconds since the last
# message received from the daemon. If keepalive_interval is set to
# -1, qemu driver will not send keepalive requests during
# peer-to-peer migration; however, the remote libvirtd can still
# send them and source libvirtd will send responses. When
# keepalive_count is set to 0, connections will be automatically

# a list of strings when a single item is in form of:
# ${PATH_TO_UEFI_FW}:${PATH_TO_UEFI_VARS}.
# Later, when libvirt creates per domain variable store, this list is
# searched for the master image. The UEFI firmware can be called
# differently for different guest architectures. For instance, it's OVMF
# for x86_64 and i686, but it's AAVMF for aarch64. The libvirt default
# follows this scheme.
