Since we've got some new CPU targets in QEMU during the last months
and years, we've got some new TARGET_xxx defines now which should
be marked as poisoned for common code.

Move function tail, about receiving next request out of the function.
Error path is simplified and nbd_co_receive_request becomes more
corresponding to its name.

This commit introduces a vhost-user-scsi backend sample application. It
must be linked with libiscsi and libvhost-user.
To use it, compile with:
$ make vhost-user-scsi
And run as follows:
$ ./vhost-user-scsi -u vus.sock -i iscsi://uri_to_target/
$ qemu-system-x86_64

These are defined in config-target.h and thus should never be

This commit introduces a vhost-user device for SCSI. This is based
on the existing vhost-scsi implementation, but done over vhost-user
instead. It also uses a chardev to connect to the backend. Unlike
vhost-scsi (today), VMs using vhost-user-scsi can be live migrated.

I've just noticed that on a SPARC host, some of the PPC guests
warn during make check:
/ppc64/prom-env/pseries:
qemu-system-ppc64: System page size 0x2000 is not enabled in
page_size_mask (0x11000). Performance may be slow
Is this really a performance problem on a TCG guest?

Hi there,
I recently migrated a Hyper-V host to qemu/kvm runing on Alpine Linux 3.6.1
(kernel 4.9.30 -with grsec patches- and qemu 2.8.1).
Almost on daily basis at least one of the guests is showing the following error
in the log and the it needs to be terminated and restarted to recover it:

This patch fixes the msa copy_[s|u]_df instruction emulation when
the destination register rd is zero. Without this patch the zero
register would get clobbered, which should never happen because it
is supposed to be hardwired to 0.
Fix this corner case by explicitly checking
1 - 100 of 162 matches
