# Echo back a unique integer value, and prepend to response a
# leading sentinel byte (0xFF) the client can check scan for.
#
# This is used by clients talking to the guest agent over the
# wire to ensure the stream is in sync and doesn't contain stale
# data from previous client. It must be issued upon initial
# connection, and after any client-side timeouts (including
# timeouts on receiving a response to this command).
#
# After issuing this request, all guest agent responses should be
# ignored until the response containing the unique integer value
# the client passed in is returned. Receival of the 0xFF sentinel
# byte must be handled as an indication that the client's
# lexer/tokenizer/parser state should be flushed/reset in
# preparation for reliably receiving the subsequent response. As
# an optimization, clients may opt to ignore all data until a
# sentinel value is receiving to avoid unnecessary processing of
# stale data.

# partially read JSON data from a previous client connection.

# @guest-sync:
#
# Echo back a unique integer value
#
# This is used by clients talking to the guest agent over the
# wire to ensure the stream is in sync and doesn't contain stale

# ignored until the provided unique integer value is returned,
# and it is up to the client to handle stale whole or
# partially-delivered JSON text in such a way that this response
# can be obtained.
#
# In cases where a partial stale response was previously
# received by the client, this cannot always be done reliably.
# One particular scenario being if qemu-ga responses are fed
# character-by-character into a JSON parser. In these situations,
# using guest-sync-delimited may be optimal.
#
# For clients that fetch responses line by line and convert them
# to JSON objects, guest-sync should be sufficient, but note that
# in cases where the channel is dirty some attempts at parsing the

qemu-ga: persist tracking of fsfreeze state via filesystem Currently, qemu-ga may die/get killed/go away for whatever reason after guest-fsfreeze-freeze has been issued, and before guest-fsfreeze-thaw has been issued. This means the only way to unfreeze the guest is via VNC/network/console access, but obtaining that access after-the-fact can often be very difficult when filesystems are frozen. Logins will almost always hang, for instance. In many cases the only recourse would be to reboot the guest without any quiescing of volatile state, which makes this a corner-case worth giving some attention to. A likely failsafe for this situation would be to use a watchdog to restart qemu-ga if it goes away. There are some precautions qemu-ga needs to take in order to avoid immediately hanging itself on I/O, however, namely, we must disable logging and defer to processing/creation of user-specific logfiles, along with creation of the pid file if we're running as a daemon. We also need to disable non-fsfreeze-safe commands, as we normally would when processing the guest-fsfreeze-freeze command. To track when we need to do this in a way that persists between multiple invocations of qemu-ga, we create a file on the guest filesystem before issuing the fsfreeze, and delete it when doing the thaw. On qemu-ga startup, we check for the existance of this file to determine the need to take the above precautions. We're forced to do it this way since a more traditional approach such as reading/writing state to a dedicated state file will cause access/modification time updates, respectively, both of which will hang if the file resides on a frozen filesystem. Both can occur even if relatime is enabled. Checking for file existence will not update the access time, however, so it's a safe way to check for fsfreeze state. An actual watchdog-based restart of qemu-ga can itself cause an access time update that would thus hang the invocation of qemu-ga, but the logic to workaround that can be handled via the watchdog, so we don't address that here (for relatime we'd periodically touch the qemu-ga binary if the file $qga_statedir/qga.state.isfrozen is not present, this avoids qemu-ga updates or the 1 day relatime threshold causing an access-time update if we try to respawn qemu-ga shortly after it goes away) Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

qemu-ga: add guest-suspend-disk As the command name implies, this command suspends the guest to disk. The suspend operation is implemented by two functions: bios_supports_mode() and guest_suspend(). Both functions are generic enough to be used by other suspend modes (introduced by next commits). Both functions will try to use the scripts provided by the pm-utils package if it's available. If it's not available, a manual method, which consists of directly writing to '/sys/power/state', will be used. To reap terminated children, a new signal handler is installed in the parent to catch SIGCHLD signals and a non-blocking call to waitpid() is done to collect their exit statuses. The statuses, however, are discarded. The approach used to query the guest for suspend support deserves some explanation. It's implemented by bios_supports_mode() and shown below: qemu-ga | create pipe | fork() ----------------- | | | | | fork() | -------------------------- | | | | | | | | exec('pm-is-supported') | | | wait() | write exit status to pipe | exit | read pipe This might look complex, but the resulting code is quite simple. The purpose of that approach is to allow qemu-ga to reap its children (semi-)automatically from its SIGCHLD handler. Implementing this the obvious way, that's, doing the exec() call from the first child process, would force us to introduce a more complex way to reap qemu-ga's children. Like registering PIDs to be reaped and having a way to wait for them when returning their exit status to qemu-ga is necessary. The approach explained above avoids that complexity.

# IMPORTANT: guest-suspend-hybrid requires QEMU to support the 'system_wakeup'
# command. Thus, it's *required* to query QEMU for the presence of the
# 'system_wakeup' command before issuing guest-suspend-hybrid.
#
# This command does NOT return a response on success. There are two options
# to check for success:
# 1. Wait for the SUSPEND QMP event from QEMU
# 2. Issue the query-status QMP command to confirm the VM status is
# "suspended"

# If hybrid suspend is not supported, Unsupported

# sending commands when the guest resumes

This command is needed to enable OpenStack to support its API for changing the admin password of guests running on KVM/QEMU.
