2013-11-14qmp: access the local QemuOptsLists for drive optionAmos Kong
Currently we have three QemuOptsList (qemu_common_drive_opts, qemu_legacy_drive_opts, and qemu_drive_opts), only qemu_drive_opts is added to vm_config_groups[]. This patch changes query-command-line-options to access three local QemuOptsLists for drive option, and merge the description items together.

2013-11-14qemu-iotests: Extend 041 for unbacked mirroringMax Reitz
Add a new test case in file 041 for mirroring unbacked images in "absolute-paths" mode. This should work, if possible, but most importantly, qemu should never crash.

2013-11-14block/drive-mirror: Check for NULL backing_hdMax Reitz
It should be possible to execute the QMP "drive-mirror" command in "none" sync mode and "absolute-paths" mode even for block devices lacking a backing file. "absolute-paths" does in fact not require a backing file to be present, as can be seen from the "top" sync mode code path. "top" basically states that the device should indeed have a backing file - however, the current code catches the case if it doesn't and then simply treats it as "full" sync mode, creating a target image without a backing file (in "absolute-paths" mode). Thus, "absolute-paths" does not imply the target file must indeed have a backing file. Therefore, the target file may be left unbacked in case of "none" sync mode as well, if the specified device is not backed either. Currently, qemu will crash trying to dereference the backing file pointer since it assumes that it will always be non-NULL in that case ("none" with "absolute-paths").

2013-11-14block: Print its file name if backing file opening failedFam Zheng
If backing file doesn't exist, the error message is confusing and misleading: $ qemu /tmp/a.qcow2 qemu: could not open disk image /tmp/a.qcow2: Could not open file: No such file or directory But... $ ls /tmp/a.qcow2 /tmp/a.qcow2 $ qemu-img info /tmp/a.qcow2 image: /tmp/a.qcow2 file format: qcow2 virtual size: 8.0G (8589934592 bytes) disk size: 196K cluster_size: 65536 backing file: /tmp/b.qcow2 Because... $ ls /tmp/b.qcow2 ls: cannot access /tmp/b.qcow2: No such file or directory This is not intuitive. It's better to have the missing file's name in the error message.

2013-11-10Revert "hw/pci: partially handle pci master abort"Marcel Apfelbaum
This reverts commit a53ae8e934cd54686875b5bcfc2f434244ee55d6. The patch being reverted introduced a low-priority memory region covering all 64 bit pci address space. This exposed the following bugs elsewhere in the code: 1. Some memory regions have INT64_MAX size, where the intent was all 64 bit address space. This results in a sub-page region, should be UINT64_MAX. 2. page table rendering in exec.c ignores physical address bits above TARGET_PHYS_ADDR_SPACE_BITS. Access outside this range (e.g. from device DMA, or gdb stub) ends up with a wrong region. Registering a region outside this range leads to page table corruption. 3. Some regions overlap PCI hole and have same priority. This only works as long as no device uses the overlapping address. It doesn't look like we can resolve all issues in time for 1.7. Let's fix the bugs first and apply afterwards for 1.8. Signed-off-by: Marcel Apfelbaum <marcel.a@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.

Options for image creation include: * log size: The size of the journaling log for VHDX. Minimum is 1MB, and it must be a multiple of 1MB. Invalid log sizes will be silently fixed by rounding up to the nearest MB. Default is 1MB. * block size: This is the size of a payload block. The range is 1MB to 256MB, inclusive, and must be a multiple of 1MB as well. Invalid sizes and multiples will be silently fixed. If '0' is passed, then a sane size is chosen (depending on virtual image size). Default is 0 (Auto-select). * subformat: - "dynamic" An image without data pre-allocated. - "fixed" An image with data pre-allocated.

The log is flushed after each entry The primary write interface, vhdx_log_write_and_flush(), performs a log write followed by an immediate flush of the log. As each log entry sector is a minimum of 4KB, partial sector writes are filled in with data from the disk write destination.

This adds support for VHDX v0 logs, as specified in Microsoft's VHDX Specification Format v1.00: https://www.microsoft.com/en-us/download/details.aspx?id=34750 The following support is added: * Log parsing, and validation - validate that an existing log is correct. * Log search - search through an existing log, to find any valid sequence of entries. * Log replay and flush - replay an existing log, and flush/clear the log when complete. The VHDX log is a circular buffer, with elements (sectors) of 4KB. A log entry is a variably-length number of sectors, that is comprised of a header and 'descriptors', that describe each sector. A log may contain multiple entries, know as a log sequence. In a log sequence, each log entry immediately follows the previous entry, with an incrementing sequence number. There can only ever be one active and valid sequence in the log. Each log entry must match the file log GUID in order to be valid (along with other criteria). Once we have flushed all valid log entries, we marked the file log GUID to be zero, which indicates a buffer with no valid entries.
