[libvirt] [PATCH v4] Add machine parameter qemu-kvm-migration for live migrate compatibility with qemu-kvm
by Alex Bligh
This patch series adds inbound migrate capability from qemu-kvm version
1.0. The main ideas are those set out in Cole Robinson's patch here:
http://pkgs.fedoraproject.org/cgit/qemu.git/tree/0001-Fix-migration-from-...
however, rather than patching statically (and breaking inbound
migration on existing machine types), I have added a new machine
parameter (qemu-kvm-migration) which when turned on affects the pc-1.0
machine type. Usage:
-machine pc-1.0,qemu-kvm-migration=on
Three aproaches are taken:
* cirrus-vga.vgamem_mb defaults to 16 rather than 8. In order to
keep -global cirrus-vga.vgamem_mb working even with
qemu-kvm-migration=on, this is monkey-patched into the default
value of the MachineState structure's compat_props list.
* In hw/timer/i8254_common.c, the VMSTATE_UINT32_TEST macro
is used to test the version for the irq_disable flags,
allowing version 3 or more, or version 2 for an inbound
migrate from qemu-kvm (only).
* In hw/acpi/piix4.c, qemu-kvm incorrectly uses version 2 for
a version 3 structure, causing acpi_load_old to be used.
acpi_load_old detects this situation based on the machine type
and restarts the attempt to load the vmstate using a
customised VMStateDescription. The above cleaner approach is
unavailable here.
The above monkey-patching must be done between the selection of
the MachineClass and the processing of the machine parameters
(on the one hand) and the processing of the compat_props list
and the globals on the command line. To do this I have added
an earlyinit function to MachineState and QEMUMachine.
I developed this on qemu 2.0 but have forward ported it (trivially)
to master. My testing has been on a VM live-migrated-to-file from
Ubuntu Precise qemu-kvm 1.0.
I have given this a moderate degree of testing but it could do
with more.
Note that certain hardware devices (including QXL) will not
migrate properly due to a fundamental difference in their internal
state between versions.
Also note that (as expected) migration from qemu-2.x to qemu-1.0
will not work, even if the machine types are the same.
Changes since v1:
* Do not use a machine type, use a machine parameter.

Add machine parameter qemu-kvm-migration for live migrate
compatibility with qemu-kvm

[libvirt] [PATCH] Add machine type pc-1.0-qemu-kvm for live migrate compatibility with qemu-kvm
by Alex Bligh
Add a machine type pc-1.0-qemu-kvm for live migrate compatibility
with qemu-kvm version 1.0.
This patch adds inbound migrate capability from qemu-kvm version
1.0. The main ideas are those set out in Cole Robinson's patch here:
http://pkgs.fedoraproject.org/cgit/qemu.git/tree/0001-Fix-migration-from-...
however, rather than patching statically (and breaking inbound
migration on existing machine types), I have added a new machine
type (pc-1.0-qemu-kvm) without affecting any other machine types.
The existing pc-1.0 machine type is renamed to pc-1.0-qemu-git,
with pc-1.0 becoming an alias for one or another, as selected
by a configure option (defaulting to pc-1.0-qemu-git, IE no
change).
Two aproaches are taken:
* In hw/timer/i8254_common.c, the VMSTATE_UINT32_TEST macro
is used to test the version for the irq_disable flags,
allowing version 3 or more, or version 2 for an inbound
migrate from qemu-kvm (only).
* In hw/acpi/piix4.c, qemu-kvm incorrectly uses version 2 for
a version 3 structure, causing acpi_load_old to be used.
acpi_load_old detects this situation based on the machine type
and restarts the attempt to load the vmstate using a
customised VMStateDescription. The above cleaner approach is
unavailable here.
I developed this on qemu 2.0 but have forward ported it (trivially)
to master. My testing has been on a VM live-migrated-to-file from
Ubuntu Precise qemu-kvm 1.0.
I have given this a moderate degree of testing but it could do
with more.
Note that certain hardware devices (including QXL) will not
migrate properly due to a fundamental difference in their internal
state between versions.
Also note that (as expected) migration from qemu-2.x to qemu-1.0
will not work, even if the machine types are the same.
Changes from v4
* Revert to using a machine type, but do not add alias machine types,
configure options, or (potentially) change the meaning of
pc-1.0 - leave this for distributions to ponder
* Add compat_props for qemu-kvm-migration to the PIIX4_PM driver
and the i8259 pit-common driver.

[libvirt] [PATCH] qemu: support nospace reason in io error event
by Eric Blake
Aeons ago (commit 34dcbbb4, v0.8.2), we added a new libvirt event
(VIR_DOMAIN_EVENT_ID_IO_ERROR_REASON) in order to tell the user WHY
the guest halted. This is because at least VDSM wants to react
differently to ENOSPC events (resize the lvm partition to be larger,
and resume the guest as if nothing had happened) from all other events
(I/O is hosed, throw up our hands and flag things as broken). At the
time this was done, downstream RHEL qemu added a vendor extension
'__com.redhat_reason', which would be exactly one of these strings:
"enospc", "eperm", "eio", and "eother". In our stupidity, we exposed
those exact strings to clients, rather than an enum, and we also
return "" if we did not have access to a reason (which was the case
for upstream qemu).
Fast forward to now: upstream qemu commit c7c2ff0c (will be qemu 2.2)
FINALLY adds a 'nospace' boolean, after discussion with multiple
projects determined that VDSM really doesn't care about distinction
between any other error types. So this patch converts 'nospace' into
the string "enospc" for compatibility with RHEL clients that were
already used to the downstream extension, while leaving the reason
blank for all other cases (no change from the status quo).
See also https://bugzilla.redhat.com/show_bug.cgi?id=1119784
* src/qemu/qemu_monitor_json.c (qewmuMonitorJSONHandleIOError):
Parse reason field from modern qemu.

[libvirt] [PATCH] util: Prepare URI formatting for libxml2 >= 2.9.2
by Martin Kletzander
Since commit 8eb55d782a2b9afacc7938694891cc6fad7b42a5 libxml2 removes
two slashes from the URI when there is no server part. This is fixed
with beb7281055dbf0ed4d041022a67c6c5cfd126f25, but only if the calling
application calls xmlSaveUri() on URI that xmlURIParse() parsed. And
that is not the case in virURIFormat(). virURIFormat() accepts
virURIPtr that can be created without parsing it and we do that when we
format network storage paths for gluster for example. Even though
virStorageSourceParseBackingURI() uses virURIParse(), it throws that data
structure right away.
Since we want to format URIs as URIs and not absolute URIs or opaque
URIs (see RFC 3986), we can specify that with a special hack thanks to
commit beb7281055dbf0ed4d041022a67c6c5cfd126f25, by setting port to -1.
This fixes qemuxml2argvtest test where the disk-drive-network-gluster
case was failing.
