Subject: [PATCH] convert_linux: start the QEMU guest agent in a
|
|
distro-specific way
|
|
|
|
The current command "service <package-name> start" does not apply to
|
|
RHEL-6; the service name ("qemu-ga") differs from the package name
|
|
("qemu-guest-agent") there.
|
|
|
|
Overhaul the logic -- detach the command from the package name; cover the
|
|
RHEL, ALT, SUSE and Debian families separately. Remove the "chkconfig"
|
|
command, as in all tested / investigated cases, it is unnecessary.
|
