This patch add an emulation for the LSI MegaRAID SAS HBA. It is using SG_IO to forward / pass through SCSI commands to the underlying block driver, so no emulation is done currently.

Other drives might want to use SCSI command emulation without going through the SCSI disk abstraction, as this imposes too many limits on the emulation.

At the present moment, my guest is running inside qemu and host is kvm intel, running Ubuntu 14.04, kernel is 4.3.0 stable. From within the guest, when I run "hdparm -i /dev/sdb" on the guest, I get: HDIO_GET_IDENTITY failed: Invalid argument as the error,but on the host, I will get the full harddisk/SSD info. Can I know how to resolve this so that the output is the same for both

This patch adds a 'raid' interface class. It is basically a clone of the existing 'scsi' interface, only allowing up to 128 disks.

This includes two kernel patches, scsi-target and IO_CMD_EPOLL_WAIT. The former is a modified version of the scsi target infrastructure in mainline. The latter enables applications to handle AIO and non-AIO fds in the same loop. blktap uses the different patch, AIO event queue patch for the same aim. The IO_CMD_EPOLL_WAIT patch will be merged into mainline (and the AIO event queue will not) so

From: Stefano Stabellini <stefano.stabellini@eu.citrix.com> When disk is a cdrom and the drive is empty the "params" node in xenstore might be missing completely: cope with it instead of segfaulting. Updated in v2: - actually removed the strchr(blkdev->params, '':'') that caused the segfault; - free all the allocated strings from xenstore before returning;

This commit delays the point at which bdrv_new (and hence blk_open on the underlying device) is called from blk_init to blk_connect. This ensures that in an inbound live migrate, the block device is not opened until it has been closed at the other end. This is in preparation for supporting devices with open/close consistency without using O_DIRECT. This commit does NOT itself change O_DIRECT

tags 490409 + patch thanks Hi, The following is the diff for my xen-3 3.2.1-2.1 NMU. It incorporates three patches from upstream and aims to fix CVE-2008-2004 aka #490409. It is not yet tested much, I would appreciate if interested parties could give it a try. I'll upload in due course. Kind regards T. diff -u xen-3-3.2.1/debian/control.md5sum xen-3-3.2.1/debian/control.md5sum ---

qemu-stubdom was stripping the prefix from the "params" xenstore key in xenstore_parse_domain_config, which was then saved stripped in a variable. In xenstore_process_event we compare the "param" from xenstore (not stripped) with the stripped "param" saved in the variable, which leads to a medium change (even if there isn't any), since we are comparing something
