2013-09-28smbios: Make multiple -smbios type= accumulate sanelyMarkus Armbruster5-65/+94
Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with value VAL to fw_cfg for each unique NAME. If NAME occurs multiple times, the last one's VAL is used (before the QemuOpts conversion, the first one was used). Multiple -smbios can add multiple fields with the same (T, NAME). SeaBIOS reads all of them from fw_cfg, but uses only the first field (T, NAME). The others are ignored. "First one wins, subsequent ones get ignored silently" isn't nice. We commonly let the last option win. Useful, because it lets you -readconfig first, then selectively override with command line options. Clean up -smbios to work the common way. Accumulate the settings, with later ones overwriting earlier ones. Put the result into fw_cfg (no more useless duplicates). Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by side effect.

2013-09-28smbios: Improve diagnostics for conflicting entriesMarkus Armbruster1-26/+17
We allow either tables or fields for the same type. Makes sense, because SeaBIOS uses fields only when no tables are present. We do this by searching the SMBIOS blob for a previously added table or field. Error messages look like this: qemu-system-x86_64: -smbios type=1,serial=42: SMBIOS type 1 table already defined, cannot add field User needs to know that "table" is defined by -smbios file=..., and "field" by -smbios type=... Instead of searching the blob, record additions of interest, and check that. Simpler, and makes better error messages possible: qemu-system-x86_64: -smbios file=smbios_type_1.bin: Can't mix file= and type= for same type qemu-system-x86_64: -smbios type=1,serial=42,serial=99: This is the conflicting setting Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Michael S.

2013-09-27qcow2: count_contiguous_clusters and compressionMax Reitz1-2/+5
The function is not intended to be used on compressed clusters and will not work correctly, if used anyway, since L2E_OFFSET_MASK is not the right mask for determining the offset of compressed clusters. Therefore, assert that the first cluster is not compressed and always include the compression flag in the mask of significant flags, i.e., stop the search as soon as a compressed cluster occurs.

2013-09-27qcow2: Always use error path in l2_allocateMax Reitz1-2/+3

2013-09-27qcow2: Don't put invalid L2 table into cacheMax Reitz1-2/+4
In l2_allocate, the fail path is executed if qcow2_cache_flush fails. However, the L2 table has not yet been fetched from the L2 table cache. The qcow2_cache_put in the fail path therefore basically gives an undefined argument as the L2 table address (in this case).

2013-09-27qcow2: Correct bitmap size in zero expansionMax Reitz1-11/+27
Since the expanded_clusters bitmap is addressed using host offsets in the underlying image file, the correct size to use for allocating the bitmap is not determined by the guest disk image but by the underlying host image file. Furthermore, this size may change during the expansion due to cluster allocations on growable image files. In this case, the bitmap needs to be resized as well to reflect the growth.

2013-09-27qemu-iotests: Add basic ability to use binary sample imagesJeff Cody3-0/+35
For image formats that are not "QEMU native", but supported for compatibility, it is useful to verify that an image created with the 'gold standard' native tool can be read / written to successfully by QEMU. In addition to testing non-native images, this could also be useful to test against image files created by older versions of QEMU. This provides a directory to store small sample images, for use by scripts in tests/qemu-iotests. Image files should be compressed with bzip2. To use a sample image from a bash script, the _use_sample_img function will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to be the decompressed sample image copy. To cleanup, call _cleanup_test_img as normal. Signed-off-by: Jeff Cody <jcody@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

QEDHeader is read, and written, directly from on-disk images via bdrv_pread()/write(). To avoid any unintentional padding, these structs should be packed. Signed-off-by: Jeff Cody <jcody@redhat.com> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

QCowHeader and QCowExtension are structs that reside in the on-disk image format, and are read and written directly via bdrv_pread()/write(), and as such should be packed to avoid any unintentional struct padding.

2013-09-25block: vpc - use QEMU_PACKED for on-disk structuresJeff Cody1-14/+14
The VHD footer and header structs (vhd_footer and vhd_dyndisk_header) are on-disk structures for the image format, and as such should be packed. Go ahead and make these typedefs as well, with the preferred QEMU naming convention, so that the packed attribute is used consistently with the struct.

This patch is qemu patch 2 to fix Xen HVM S3 bug, adding qemu xen logic. When qemu wakeup, qemu xen logic is notified and hypercall to xen hypervisor to unpause domain.

2013-09-25qemu: Adjust qemu wakeupLiu, Jinsong3-10/+12
Currently Xen hvm s3 has a bug coming from the difference between qemu-traditioanl and qemu-xen. For qemu-traditional, the way to resume from hvm s3 is via 'xl trigger' command. However, for qemu-xen, the way to resume from hvm s3 inherited from standard qemu, i.e. via QMP, and it doesn't work under Xen. The root cause is, for qemu-xen, 'xl trigger' command didn't reset devices, while QMP didn't unpause hvm domain though they did qemu system reset. We have two qemu patches and one xl patch to fix Xen hvm s3 bug. This patch is the qemu patch 1. It adjusts qemu wakeup so that Xen s3 resume logic (which will be implemented at qemu patch 2) will be notified after qemu system reset.
