From b7fc90f3d4f0d61281312c5d05859ee2de8fc8be Mon Sep 17 00:00:00 2001
From: Olaf Hering <olaf@aepfle.de>
Date: Mon, 10 Feb 2014 12:47:26 +0100
Subject: libxc: pass errno to callers of xc_domain_save
Callers of xc_domain_save use errno to print diagnostics if the call
fails. But xc_domain_save does not preserve the actual errno in case of
a failure.
This change preserves errno in all cases where code jumps to the label
"out". In addition a new label "exit" is added to catch also code which
used to do just "return 1".
Now libxl_save_helper:complete can print the actual error string.
Note: some of the functions used in xc_domain_save do not use errno to
indicate a reason. In these cases the errno remains undefined as it used
to be without this change.

References: FATE#316071
Subject: libxl: add option for discard support to xl disk configuration
Handle new option discard=on|off for disk configuration. It is supposed
to disable discard support if file based backing storage was
intentionally created non-sparse to avoid fragmentation of the file.
The option is a boolean and intended for the backend driver. A new
boolean property "discard-enable" is written to the backend node. An
upcoming patch for qemu will make use of this property. The kernel
blkback driver may be updated as well to disable discard for phy based
backing storage.
This change does not break ABI. Instead of adding a new member ->discard_enable
to struct libxl_device_disk the existing ->readwrite member is reused.

From 77deb80879859ed279e24a790ec08e9c5d37dd0e Mon Sep 17 00:00:00 2001

Subject: libxl: set migration constraints from cmdline
Add new options to xl migrate to control the process of migration.
The intention is to optionally abort the migration if it takes too long
to migrate a busy guest due to the high number of new dirty pages.
Currently the guest is suspended to transfer the remaining dirty pages.
The suspend/resume cycle will cause a time jump. This transfer can take
a long time, which can confuse the guest if the time jump is too far.
The new options allow to override the built-in default values, which are
not changed by this patch.
--max_iters <number> Number of iterations before final suspend (default: 30)
--max_factor <factor> Max amount of memory to transfer before final suspend (default: 3*RAM)
--min_remaing <pages> Number of dirty pages before stop&copy (default: 50)
--abort_if_busy Abort migration instead of doing final suspend.
The changes to libxl change the API, handle LIBXL_API_VERSION == 0x040200.
v8:
- merge --min_remaing changes
- tools/libxc: print stats if migration is aborted
- use special _suse version of lib calls to preserve ABI
v7:
- remove short options
- update description of --abort_if_busy in xl.1
- extend description of --abort_if_busy in xl help
- add comment to libxl_domain_suspend declaration, props is optional
v6:
- update the LIBXL_API_VERSION handling for libxl_domain_suspend
change it to an inline function if LIBXL_API_VERSION is defined to 4.2.0
- rename libxl_save_properties to libxl_domain_suspend_properties
- rename ->xlflags to ->flags within that struct
v5:
- adjust libxl_domain_suspend prototype, move flags, max_iters,
max_factor into a new, optional struct libxl_save_properties
- rename XCFLAGS_DOMSAVE_NOSUSPEND to XCFLAGS_DOMSAVE_ABORT_IF_BUSY
- rename LIBXL_SUSPEND_NO_FINAL_SUSPEND to LIBXL_SUSPEND_ABORT_IF_BUSY
- rename variables no_suspend to abort_if_busy
- rename option -N/--no_suspend to -A/--abort_if_busy
- update xl.1, extend description of -A option
v4:
- update default for no_suspend from None to 0 in XendCheckpoint.py:save
- update logoutput in setMigrateConstraints
- change xm migrate defaults from None to 0
- add new options to xl.1
- fix syntax error in XendDomain.py:domain_migrate_constraints_set
- fix xm migrate -N option name to match xl migrate
v3:
- move logic errors in libxl__domain_suspend and fixed help text in
cmd_table to separate patches
- fix syntax error in XendCheckpoint.py
- really pass max_iters and max_factor in libxl__xc_domain_save
- make libxl_domain_suspend_0x040200 declaration globally visible
- bump libxenlight.so SONAME from 2.0 to 2.1 due to changed
libxl_domain_suspend
v2:
- use LIBXL_API_VERSION and define libxl_domain_suspend_0x040200
- fix logic error in min_reached check in xc_domain_save
- add longopts
- update --help text
- correct description of migrate --help text

References: FATE#316071
Subject: [RFC] qemu-upstream: add discard support for xen_disk
Subject: qemu-upstream: add discard support for xen_disk
Implement discard support for xen_disk. It makes use of the existing
discard code in qemu.
The discard support is enabled unconditionally. But it would be worth to
have a knob to disable it in case the backing file was intentionally
created non-sparse to avoid fragmentation.
How could this be knob be passed from domU.cfg:disk=[] to the actual
qemu process? Perhaps introduce an option discard=on|off|ignore|unmap.
The discard support is enabled unconditionally. The tool stack may provide a
property "discard-enable" in the backend node to optionally disable discard
support. This is helpful in case the backing file was intentionally created
non-sparse to avoid fragmentation.
v2:
rename xenstore property from discard_enable to discard-enable
move discard_req to case BLKIF_OP_DISCARD

description:
tools: add xm migrate --log_progress option
xc_domain_save does print progress messages. These verbose messages are
disabled per default to avoid flood in xend.log. Sometimes it is helpful
to see progress when migrating large and busy guests. So add a new
option to xm migrate to actually enable the printing of progress
messsages.
xl migrate is not modified with this change because it does not use the
stdio logger.

description:
tools: set migration constraints from cmdline
Add new options to xm/xl migrate to control the process of migration.
The intention is to optionally abort the migration if it takes too long
to migrate a busy guest due to the high number of dirty pages. Currently
the guest is suspended to transfer the remaining dirty pages. This
transfer can take too long, which can confuse the guest if its suspended
for too long.
-M <number> Number of iterations before final suspend (default: 30)
--max_iters <number>
-m <factor> Max amount of memory to transfer before final suspend (default: 3*RAM)
--max_factor <factor>
-A Abort migration instead of doing final suspend.
--abort_if_busy
The changes to libxl change the API, handle LIBXL_API_VERSION == 0x040200.
TODO:
eventually add also --min_remaining (default value 50) in a seperate patch
v6:
- update the LIBXL_API_VERSION handling for libxl_domain_suspend
change it to an inline function if LIBXL_API_VERSION is defined to 4.2.0
- rename libxl_save_properties to libxl_domain_suspend_properties
- rename ->xlflags to ->flags within that struct
v5:
- adjust libxl_domain_suspend prototype, move flags, max_iters,
max_factor into a new, optional struct libxl_save_properties
- rename XCFLAGS_DOMSAVE_NOSUSPEND to XCFLAGS_DOMSAVE_ABORT_IF_BUSY
- rename LIBXL_SUSPEND_NO_FINAL_SUSPEND to LIBXL_SUSPEND_ABORT_IF_BUSY
- rename variables no_suspend to abort_if_busy
- rename option -N/--no_suspend to -A/--abort_if_busy
- update xl.1, extend description of -A option
v4:
- update default for no_suspend from None to 0 in XendCheckpoint.py:save
- update logoutput in setMigrateConstraints
- change xm migrate defaults from None to 0
- add new options to xl.1
- fix syntax error in XendDomain.py:domain_migrate_constraints_set
- fix xm migrate -N option name to match xl migrate
v3:
- move logic errors in libxl__domain_suspend and fixed help text in
cmd_table to separate patches
- fix syntax error in XendCheckpoint.py
- really pass max_iters and max_factor in libxl__xc_domain_save
- make libxl_domain_suspend_0x040200 declaration globally visible
- bump libxenlight.so SONAME from 2.0 to 2.1 due to changed
libxl_domain_suspend
v2:
- use LIBXL_API_VERSION and define libxl_domain_suspend_0x040200
- fix logic error in min_reached check in xc_domain_save
- add longopts
- update --help text
- correct description of migrate --help text

description:
tools: set number of dirty pages during migration
If a guest is really busy it will not reach the low number of remaining
50 dirty pages for the final suspend. As a result the guest is either
suspendend for a long time during the final transfer, or if the number
of iterations is increased the migration will take a long time.
Add a new option xm/xl migrate --min_remaing <pages> to increase the
default from command line. The default of 50 is 200kb, which is
appearently an arbitrary number. With todays network speeds a larger
block of memory can be transfered quickly without causing too much
suspension time. This knob gives the admin the chance to adapt the
suspension time to the given workload.
The existing default of 50 pages is not altered by this change.

Subject: xend/pvscsi: recognize also SCSI CDROM devices
Attaching a CDROM device with 'xm scsi-attach domU /dev/sr0 0:0:0:0'
fails because for some reason the sr driver was not handled at all in
the match list. With the change the above command succeeds and the
device is attached.

From aa0cecb067ca6077c67cfc13f0ce31af7a3b72bb Mon Sep 17 00:00:00 2001
From: Olaf Hering <olaf@aepfle.de>
Date: Mon, 10 Feb 2014 09:43:40 +0100
Subject: xend: set migration constraints from cmdline
xend part of required libxl change to tweak parameters of xc_domain_save
Add xm migrate --log_progress option. xc_domain_save does print progress
messages. These verbose messages are disabled per default to avoid flood
in xend.log. Sometimes it is helpful to see progress when migrating
large and busy guests. So add a new option to xm migrate to actually
enable the printing of progress messsages.
Print messages from xc_save with xc_report. Make use of xc_report in
xc_save to log also pid if some error occoured.
