2010-12-17ide: split ide command interpretation offAlexander Graf2-6/+16
The ATA command interpretation code can be used for PATA and SATA interfaces alike. So let's split it out into a separate function. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-12-17qemu-img.c: Clean up handling of image size in img_create()Jes Sorensen1-6/+17
This cleans up the handling of image size in img_create() by parsing the value early, and then only setting it once if a value has been added as the last argument to the command line.

2010-12-17Introduce strtosz_suffix()Jes Sorensen2-3/+21
This introduces strtosz_suffix() which allows the caller to specify a default suffix in case the non default of MB is wanted. strtosz() is kept as a wrapper for strtosz_suffix() which keeps it's current default of MB.

2010-12-17block: Fix the use of protocols in backing filesStefan Hajnoczi1-3/+11
Backing filenames may contain a protocol. The code currently doesn't consider this case and produces filenames that embed "<protocol>:". Don't combine filenames if the backing filename contains a protocol. Based on an earlier patch by Anthony Liguori <aliguori@us.ibm.com>.

2010-12-17block: Introduce path_has_protocol() functionStefan Hajnoczi1-28/+36
The bdrv_find_protocol() function returns NULL if an unknown protocol name is given. It returns the "file" protocol when the filename contains no protocol at all. This makes it difficult to distinguish between paths which contain a protocol and those which do not. Factor out a helper function that tests whether or not a filename has a protocol. The next patch makes use of this function. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-12-17blockdev: check dinfo ptr before usingRyan Harper1-2/+4
If a user decides to punish a guest by revoking its block device via drive_del, and subsequently also attempts to remove the pci device backing it, and the device is using blockdev_auto_del() then we get a segfault when we attempt to access dinfo->auto_del.[1] The fix is to check if drive_get_by_blockdev() actually returns a valid dinfo pointer or not. 1.

2010-12-14ceph/rbd block driver for qemu-kvmChristian Brunner4-0/+1183
RBD is an block driver for the distributed file system Ceph (http://ceph.newdream.net/). This driver uses librados (which is part of the Ceph server) for direct access to the Ceph object store and is running entirely in userspace (Yehuda also wrote a driver for the linux kernel, that can be used to access rbd volumes as a block device).

This consolidates the printing of block driver options in print_block_option_help() which is called from both img_create() and img_convert().

2010-12-14block: Make bdrv_create_file() ':' handling consistentStefan Hajnoczi1-1/+1
Filenames may start with "<protocol>:" to explicitly use a protocol like nbd. Filenames with unknown protocols are rejected in most of QEMU except for bdrv_create_file(). Even if a file with an invalid filename can be created, QEMU cannot use it since all the other relevant functions reject such paths. Make bdrv_create_file() consistent.

2010-12-12Watchdog: disable watchdog timer when hard-rebooting a guest.Richard W.M. Jones2-5/+20
This commit causes the watchdog timer to be reset when a guest is hard-rebooted. The failure case previously was as follows: (a) guest boots, watchdog is enabled (b) guest does a reset eg: echo 'b' > /proc/sysrq-trigger (note that an ordinary /sbin/reboot wouldn't hit this case since as the watchdog daemon is shut down, the daemon would properly disable the watchdog device) (c) the reboot takes longer than the remaining time on the watchdog (d) the watchdog therefore fires during the reboot (e) probably the VM would just reboot again at this point which is pretty benign, but it could depend on the action that the user had selected for the watchdog Now we use the qdev reset function to register a reset handler which disables the timer. Note the handler is called _either_ just after init _or_ when the guest reboots. In the i6300esb case there is a small refactoring of the code so that the device's internal state is now fully restored to defaults on a reboot. Signed-off-by: Richard W.M.

Change fw_cfg_add_file() to get full file path as a parameter instead of building one internally. Two reasons for that. First caller may need to know how file is named. Second this moves policy of file naming out from fw_cfg. Platform may want to use more then two levels of directories for instance.
