2012-04-30qemu-ga: persist tracking of fsfreeze state via filesystemMichael Roth
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>
2012-04-30qemu-ga: add a whitelist for fsfreeze-safe commandsMichael Roth
Currently we rely on fsfreeze/thaw commands disabling/enabling logging then having other commands check whether logging is disabled to avoid executing if they aren't safe for running while a filesystem is frozen. Instead, have an explicit whitelist of fsfreeze-safe commands, and consolidate logging and command enablement/disablement into a pair of helper functions: ga_set_frozen()/ga_unset_frozen() Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
2012-04-30qemu-ga: improve recovery options for fsfreezeMichael Roth
guest-fsfreeze-thaw relies on state information obtained from guest-fsfreeze-freeze to determine what filesystems to unfreeze. This is unreliable due to the fact that that state does not account for FIFREEZE being issued by other processes, or previous instances of qemu-ga. This means in certain situations we cannot thaw filesystems even with a responsive qemu-ga instance at our disposal. This patch allows guest-fsfreeze-thaw to be issued unconditionally. It also adds some additional logic to allow us to thaw filesystems regardless of how many times the filesystem's "frozen" refcount has been incremented by any guest processes. Also, guest-fsfreeze-freeze now operates atomically: on success all freezable filesystems are frozen, and on error all filesystems are thawed. The ambiguous "GUEST_FSFREEZE_STATUS_ERROR" state is no longer entered. Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

2012-04-27qemu-iotests: add block-stream speed value test caseStefan Hajnoczi
Add tests to exercise the InvalidParameter 'speed' error code path, as well as the regular success case for setting the speed. The block-stream 'speed' parameter allows the speed limit of the job to be applied immediately when the job starts instead of issuing a separate block-job-set-speed command later. If the parameter has an invalid value we expect to get an error and the job is not created. It turns out that cancelling a block job is a common operation in these test cases, let's extract a cancel_and_wait() function instead of duplicating the QMP commands.

2012-04-27block: use Error mechanism instead of -errno for block_job_create()Stefan Hajnoczi
The block job API uses -errno return values internally and we convert these to Error in the QMP functions. This is ugly because the Error should be created at the point where we still have all the relevant information. More importantly, it is hard to add new error cases to this case since we quickly run out of -errno values without losing information. Go ahead and use Error directly and don't convert later.
