2014-11-24Revert "qemu-img info: show nocow info"Kevin Wolf1-4/+1
This reverts commit 000c4dfff4d7686e2fba3066a477a1290ed60622. The main reason for reverting this commit before the 2.2 release is that it adds a QAPI interface that we don't want to keep: The 'nocow' flag doesn't generally make sense for block nodes, but only for the raw-posix driver. It should therefore be part of ImageInfoSpecific rather than ImageInfo. The commit contains more problems, but unlike the API stability issue they wouldn't justify reverting it.

2014-09-26qapi: dealloc visitor, implement visit_start_unionMichael Roth1-0/+26
If the .data field of a QAPI Union is NULL, we don't need to free any of the union fields. Make use of the new visit_start_union interface to access this information and instruct the generated code to not visit these fields when this occurs.

2014-09-26qapi: add visit_start_union and visit_end_unionMichael Roth1-0/+15
In some cases an input visitor might bail out on filling out a struct for various reasons, such as missing fields when running in strict mode. In the case of a QAPI Union type, this may lead to cases where the .kind field which encodes the union type is uninitialized. Subsequently, other visitors, such as the dealloc visitor, may use this .kind value as if it were initialized, leading to assumptions about the union type which in this case may lead to segfaults. For example, freeing an integer value. However, we can generally rely on the fact that the always-present .data void * field that we generate for these union types will always be NULL in cases where .kind is uninitialized (at least, there shouldn't be a reason where we'd do this purposefully). So pass this information on to Visitor implementation via these optional start_union/end_union interfaces so this information can be used to guard against the situation above. We will make use of this information in a subsequent patch for the dealloc visitor.

2014-09-22block: delete cow block driverStefan Hajnoczi1-3/+2
This patch removes support for the cow file format. Normally we do not break backwards compatibility but in this case there is no impact and it is the most logical option. Extraordinary claims require extraordinary evidence so I will show why removing the cow block driver is the right thing to do. The cow file format is the disk image format for Usermode Linux, a way of running a Linux system in userspace. The performance of UML was never great and it was hacky, but it enjoyed some popularity before hardware virtualization support became mainstream. QEMU's block/cow.c is supposed to read this image file format. Unfortunately the file format was underspecified: 1. Earlier Linux versions used the MAXPATHLEN constant for the backing filename field. The value of MAXPATHLEN can change, so Linux switched to a 4096 literal but QEMU has a 1024 literal. 2. Padding was not used on the header struct (both in the Linux kernel and in QEMU) so the struct layout varied across architectures. In particular, i386 and x86_64 were different due to int64_t alignment differences. Linux now uses __attribute__((packed)), QEMU does not. Therefore: 1. QEMU cow images do not conform to the Linux cow image file format. 2. cow images cannot be shared between different host architectures. This means QEMU cow images are useless and QEMU has not had bug reports from users actually hitting these issues. Let's get rid of this thing, it serves no purpose and no one will be affected.

Nonetheless, even an image only read from may of course be corrupted and this can be detected during normal operation. In this case, a non-fatal event should be emitted, but the image should not be marked corrupt (in accordance to "fatal" set to false).

BLOCK_IO_ERROR events are logged by libvirt, which helps with post mortem analysis of guests. However, one information that we miss today is a human readable string describing the cause of the I/O error. This commit adds that string it to BLOCK_IO_ERROR.

2014-09-10block: extend BLOCK_IO_ERROR event with nospace indicatorLuiz Capitulino1-1/+7
Management software, such as RHEV's vdsm, want to be able to allocate disk space on demand. The basic use case is to start a VM with a small disk and then the disk is enlarged when QEMU hits a ENOSPC condition. To this end, the management software has to be notified when QEMU encounters ENOSPC. The solution implemented by this commit is simple: it extends the BLOCK_IO_ERROR with a 'nospace' key, which is true when QEMU is stopped due to ENOSPC. Note that support for querying this event is already present in query-block by means of the 'io-status' key. Also, the new 'nospace' BLOCK_IO_ERROR field shares the same semantics with 'io-status', which basically means that werror= has to be set to either 'stop' or 'enospc' to enable 'nospace'. Finally, this commit also updates the 'io-status' key doc in the schema with a list of supported device models.

2014-07-01block: add backing-file option to block-streamJeff Cody1-2/+17
On some image chains, QEMU may not always be able to resolve the filenames properly, when updating the backing file of an image after a block job. For instance, certain relative pathnames may fail, or drives may have been specified originally by file descriptor (e.g. /dev/fd/???), or a relative protocol pathname may have been used. In these instances, QEMU may lack the information to be able to make the correct choice, but the user or management layer most likely does have that knowledge. With this extension to the block-stream api, the user is able to change the backing file of the active layer as part of the block-stream operation. This allows the change to be 'safe', in the sense that if the attempt to write the active image metadata fails, then the block-stream operation returns failure, without disrupting the guest. If a backing file string is not specified in the command, the backing file string to use is determined in the same manner as it was previously.

2014-07-01block: add QAPI command to allow live backing file changeJeff Cody1-0/+26
This allows a user to make a live change to the backing file recorded in an open image. The image file to modify can be specified 2 ways: 1) image filename 2) image node-name Note: this does not cause the backing file itself to be reopened; it merely changes the backing filename in the image file structure, and in internal BDS structures. It is the responsibility of the user to pass a filename string that can be resolved when the image chain is reopened, and the filename string is not validated. A good analogy for this command is that it is a live version of 'qemu-img rebase -u', with respect to changing the backing file string. [Jeff is offline so I respun this patch in his absence.

2014-06-23qapi event: convert other BLOCK_JOB eventsWenchao Xia1-0/+71
Since BLOCK_JOB_COMPLETED, BLOCK_JOB_CANCELLED, BLOCK_JOB_READY are related, convert them in one patch. The block_job_event_* functions are used to keep encapsulation of BlockJob structure.

2014-06-23qapi: adjust existing definesWenchao Xia1-0/+16
In order to let event defines use existing types later, instead of redefine new ones, some old type defines for spice and vnc are changed, and BlockErrorAction is moved from block.h to qapi schema. Note that BlockErrorAction is not merged with BlockdevOnError. At this point, VncInfo is not made a child of VncBasicInfo, because VncBasicInfo has mandatory fields where VncInfo makes them optional.
