* xen: Don't peek behind the BlockDriverState abstractionMarkus Armbruster2012-06-151-3/+3
| | | | | | | | | | | | | | | First offender is xen_config_dev_blk()'s use of disk->bdrv->filename. Get the filename from disk->opts instead. Same result, except for snapshots: there, we now get the filename specified by the user instead of the name of the temporary image created by bdrv_open(). Should be an improvement. Second offender is blk_init()'s use of blkdev->bs->drv->format_name. Simply use the appropriate interface to get the format name.

* xen: Don't change -drive if=xen device name during machine initMarkus Armbruster2012-06-151-5/+4
| | | | | | | | | | | | | A "top" BlockDriverState has a non-empty device_name. If the user doesn't specify one with -drive parameter id, the system supplies a default name. xen_config_dev_blk() changes this name, during machine initialization. Naughty. Don't do that.

* Use glib memory allocation and free functionsAnthony Liguori2011-08-201-2/+2

* net: Consistently use qemu_macaddr_default_if_unsetJan Kiszka2011-07-231-2/+2
| | | | | | | | | | | | | | | | | Drop the open-coded MAC assignment from net_init_nic and replace it with standard qemu_macaddr_default_if_unset which is also used by qdev. That avoid creating colliding MACs when instantiating NICs via different mechanisms. This change requires to store the MAC as MACAddr in NICInfo, and the remaining nd_table users need to be updated. Based on suggestion by Peter Maydell.

* blockdev: Store -drive option media in DriveInfoMarkus Armbruster2011-05-191-1/+1
| | | | | | | | | | | | | | | | DriveInfo is closely tied to -drive, and like -drive, it mixes information about host and guest part of the block device. Unlike DriveInfo, BlockDriverState should be about the host part only. One of the remaining guest bits there is the "type hint". -drive option media sets it, and qdevs "ide-drive", "scsi-disk" and non-qdev IF_XEN devices check it to pick HD vs. CD. Communicate -drive option media via new DriveInfo member media_cd instead. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
* Rearrange block headersBlue Swirl2010-08-241-0/+2
| | | | | | | | | Changing block.h or blockdev.h resulted in recompiling most objects. Move DriveInfo typedef and BlockInterfaceType enum definitions to qemu-common.h and rearrange blockdev.h use to decrease churn. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* Revert "Convert atexit users to exit_notifier"Anthony Liguori2010-03-211-1/+1
| | | | | | | | | | | | This reverts commit d7234f4d7e373a708e1df9ab565a71b71b189025. Conflicts: hw/xen_machine_pv.c This should have never been committed. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* Convert atexit users to exit_notifierAnthony Liguori2010-03-191-1/+1
| | | | | | | | All of these users have global state so we really don't see a benefit from exit_notifier. However, using exit_notifier means that there's one less justification for having global state in the first place. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* Fix sys-queue.h conflict for goodBlue Swirl2009-09-121-4/+4
| | | | | | | | | | | | | | | Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* xen: pv domain builder. (Gerd Hoffmann)aliguori2009-04-221-0/+29
| | | | | | | | | | | | This adds domain building support for paravirtual domains to qemu. This allows booting xen guests directly with qemu, without Xend and the management stack.

* xen: blk & nic configuration via cmd line. (Gerd Hoffmann)aliguori2009-04-221-0/+142
This patch makes qemu create backend and frontend device entries in xenstore for devices configured on the command line. It will use qdisk and qnic backend names, so the qemu internal backends will be used. Disks can be created using -drive if=xen,file=... Nics can be created using -net nic,macaddr=...
