+# For local or direct-attached storage, it is recommended that you use
+# writethrough (default) mode, as it ensures data integrity and has
+# acceptable
+# I/O performance for applications running in the guest, especially
+# for read
+# operations. However, caching mode none is recommended for remote NFS
+# storage,
+# because direct I/O operations (O_DIRECT) perform better than
+# synchronous I/O
+# operations (with O_SYNC). Caching mode none effectively turns all
+# guest I/O
+# operations into direct I/O operations on the host, which is the NFS
+# client in
+# this environment.
+#
+# Possible cache modes:
+#
+# * default: Same as writethrough.
+# * none: With caching mode set to none, the host page cache is
+# disabled, but
+#   the disk write cache is enabled for the guest. In this mode, the
+# write
+#   performance in the guest is optimal because write operations
+# bypass the host
+#   page cache and go directly to the disk write cache. If the disk
+# write cache
+#   is battery-backed, or if the applications or storage stack in the
+# guest
+#   transfer data properly (either through fsync operations or file
+# system
+#   barriers), then data integrity can be ensured. However, because
+# the host
+#   page cache is disabled, the read performance in the guest would
+# not be as
+#   good as in the modes where the host page cache is enabled, such as
+#   writethrough mode. Shareable disk devices, like for a multi-
+# attachable block
+#   storage volume, will have their cache mode set to 'none'
+# regardless of
+#   configuration.
+# * writethrough: writethrough mode is the default caching mode. With
+#   caching set to writethrough mode, the host page cache is enabled,
+# but the
+#   disk write cache is disabled for the guest. Consequently, this
+# caching mode
+#   ensures data integrity even if the applications and storage stack
+# in the
+#   guest do not transfer data to permanent storage properly (either
+# through
+#   fsync operations or file system barriers). Because the host page
+# cache is
+#   enabled in this mode, the read performance for applications
+# running in the
+#   guest is generally better. However, the write performance might be
+# reduced

+# Specific cache modes to use for different disk types.
+#
+# For example: file=directsync,block=none,network=writeback
+#
+# For local or direct-attached storage, it is recommended that you use
+# writethrough (default) mode, as it ensures data integrity and has
+# acceptable
+# I/O performance for applications running in the guest, especially
+# for read
+# operations. However, caching mode none is recommended for remote NFS
+# storage,
+# because direct I/O operations (O_DIRECT) perform better than
+# synchronous I/O
+# operations (with O_SYNC). Caching mode none effectively turns all
+# guest I/O
+# operations into direct I/O operations on the host, which is the NFS
+# client in
+# this environment.
+#
+# Possible cache modes:
+#
+# * default: Same as writethrough.
+# * none: With caching mode set to none, the host page cache is
+# disabled, but
+#   the disk write cache is enabled for the guest. In this mode, the
+# write
+#   performance in the guest is optimal because write operations
+# bypass the host
+#   page cache and go directly to the disk write cache. If the disk
+# write cache
+#   is battery-backed, or if the applications or storage stack in the
+# guest
+#   transfer data properly (either through fsync operations or file
+# system
+#   barriers), then data integrity can be ensured. However, because
+# the host
+#   page cache is disabled, the read performance in the guest would
+# not be as
+#   good as in the modes where the host page cache is enabled, such as
+#   writethrough mode. Shareable disk devices, like for a multi-
+# attachable block
+#   storage volume, will have their cache mode set to 'none'
+# regardless of
+#   configuration.
+# * writethrough: writethrough mode is the default caching mode. With
+#   caching set to writethrough mode, the host page cache is enabled,
+# but the
+#   disk write cache is disabled for the guest. Consequently, this
+# caching mode
+#   ensures data integrity even if the applications and storage stack
+# in the
+#   guest do not transfer data to permanent storage properly (either
+# through
+#   fsync operations or file system barriers). Because the host page
+# cache is
+#   enabled in this mode, the read performance for applications
+# running in the
+#   guest is generally better. However, the write performance might be
+# reduced
+#   because the disk write cache is disabled.
+# * writeback: With caching set to writeback mode, both the host page
+# cache
+#   and the disk write cache are enabled for the guest. Because of
+# this, the
+#   I/O performance for applications running in the guest is good, but
+# the data
+#   is not protected in a power failure. As a result, this caching
+# mode is
+#   recommended only for temporary data where potential data loss is
+# not a
+#   concern.
+# * directsync: Like "writethrough", but it bypasses the host page
+# cache.
+# * unsafe: Caching mode of unsafe ignores cache transfer operations
+#   completely. As its name implies, this caching mode should be used
+# only for
+#   temporary data where data loss is not a concern. This mode can be
+# useful for
+#   speeding up guest installations, but you should switch to another

+# 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
+# closed after keepalive_interval seconds of inactivity without
