SUSE adjustments to qemu.conf
|
|
|
|
This patch contains SUSE-specific adjustments to the upstream
|
|
qemu.conf configuration file. In the future, it might make
|
|
sense to separate these changes into individual patches (e.g.
|
|
suse-qemu-conf-secdriver.patch, suse-qemu-conf-lockmgr.patch,
|
|
etc.), but for now they are all lumped together in this
|
|
single patch.

-# In order to prevent accidentally starting two domains that
|
|
-# share one writable disk, libvirt offers two approaches for
|
|
-# locking files. The first one is sanlock, the other one,
|
|
-# virtlockd, is then our own implementation. Accepted values
|
|
-# are "sanlock" and "lockd".
|
|
+# SUSE note:
|
|
+# Two lock managers are supported: lockd and sanlock. lockd, which
|
|
+# is provided by the virtlockd service, uses advisory locks (flock(2))
|
|
+# to protect virtual machine disks. sanlock uses the notion of leases
|
|
+# to protect virtual machine disks and is more appropriate in a SAN
|
|
+# environment.
|
|
+#
|
|
+# For most deployments that require virtual machine disk protection,
|
|
+# lockd is recommended since it is easy to configure and the virtlockd
|
|
+# service can be restarted without terminating any running virtual
|
|
+# machines. sanlock, which may be preferred in some SAN environments,
|
|
+# has the disadvantage of not being able to be restarted without
|
|
+# first terminating all virtual machines for which it holds leases.
