I am pleased to announce the release of Xen 4.4.1, 4.3.3 and 4.2.5. We recommend that all users of the 4.4, 4.3 and 4.2 stable series update to the latest point release.
On FreeBSD polling a master pty while the other end is not connected with G_IO_OUT only results in an endless wait.の修正
This patch allows an HVM domain to be created with multiple serial ports.
Allow the "serial" key to accept a list of serial ports, and pass them in using the new serial_list domain build element.
Currently in xl.cfg, use 'root' and 'extra' to generate the command line.
Direct kernel boot allows booting directly from a kernel and initrd
stored in the host physical machine OS, allowing command line arguments
to be passed directly. PV guest direct kernel boot is supported. HVM
guest direct kernel boot is supported with limitation (it's supported
when using qemu-xen and default BIOS 'seabios'; not supported in case of
stubdom-dm and old rombios.)
As pointed out by Jan Beulich in
http://lists.xen.org/archives/html/xen-devel/2014-08/msg01269.html:
"Read-modify-write instructions absolutely need to be treated as read
accesses, yet hardware doesn't guarantee to tell us so (they may
surface as just write accesses)." This patch addresses the issue in
both the VMX and the SVM side.
VMX: Treat all write data access violations also as read violations (in
addition to those that were already reported as read violations).
SVM: Refine the meaning of read data access violations to distinguish
between read/write and instruction fetch access violations.
With this patch both VMX and SVM specific nested page fault handling code
reports violations the same way, thus abstracting the hardware specific
behaviour from the layers above.
Update the protocol description of the pvSCSI framework used to pass through
SCSI devices to a guest (pv or hvm).
The main changes are:
- added comments
- add support for larger SG-lists by putting them in an own granted page
- deprecate VSCSIIF_ACT_SCSI_SG_PRESET action with related structures
- add ref_rqid for action VSCSIIF_ACT_SCSI_ABORT to be able to specify the
request to abort
- deprecate timeout_per_command as this really should be handled by the
backend in case of default settings or by the guest domain by aborting a
long running command
This update is related to the rework of the pvSCSI backend and frontend drivers
in the Linux kernel. This interface version is included in that rework, too.
