[libvirt] [RFC] powerpc : Add support for VM in compat mode
by Prerna Saxena 19 Aug '14

19 Aug '14

PowerISA allows processors to run VMs in binary compatibility ("compat") mode supporting an older version of ISA. Eg,in compatibility mode, a POWER8 host can run a "Power7" VM,conforming to PowerISA v2.06, while a POWER7 host can run a "POWER6" VM, conforming to PowerISA v2.05. QEMU has recently added support to explicitly denote a VM running in compatibility mode through commit 6d9412ea. Now, a "compat" mode VM can be run by invoking this qemu commandline on a POWER8 host: -cpu host,compat=power7 as against the older specification of "-cpu power7". However, running in compatibility mode is not identical to running natively on an older processor. Hence the virtualization stack needs to explicitly provide for a compat-mode VM. This patch allows libvirt to extend the "fallback" semantics of cpu model to describe this new mode for PowerKVM guests. Additionally with the new scheme of things, qemu doesn't provide a way to query for the supported compat models and models returned when querying with '-cpu ?' are no longer valid. Hence removing the check cpuModelIsAllowed() for now. When a user wants to request a power7 vm to run in compatibility mode on a Power8 host, this can be described in XML as follows : <cpu mode='custom' match='exact'> <model fallback='compat'>power7</model> </cpu> An alternative approach could be to leave the libvirt XML intact, and merely change the backend qemu command generation when the VM-requested cpu does not match the host processor. Looking forward to suggestions on how this can best be implemented.. Signed-off-by: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> Signed-off-by: Pradipta Kr.

[libvirt] [PATCH] cmdMigrate: move vshConnect before vshWatchJob
by Chunyan Liu 19 Aug '14

19 Aug '14

A possible fix to issue: http://www.redhat.com/archives/libvir-list/2014-August/thread.html#00227 While doing migration on KVM host, found problem sometimes: VM is already running on the target host and disappears from source host, but 'virsh migrate' command line hangs, cannot exit normally. If pressing "ENTER" key, it will exit. The code hangs at tools/virsh-domain.c: cmdMigrate ->vshWatchJob->poll(): poll() is trying to select pipe_fd, which is used to receive message from doMigrate thread. In debugging, found that doMigrate finishes and at the end it does call safewrite() to write the retval ('0' or '1') to pipe_fd, and the write is completed. But cmdMigrate poll() cannot get the event. If pressing "ENTER" key, poll() can get the event and select pipe_fd, then command line can exit. In current code, authentication thread which is called by vshConnect will use stdin, and at the same time, in cmdMigrate main process, poll() is listening to stdin, that probably affect poll() to get pipe_fd event. Better to move authentication before vshWatchJob. With this change, above problem does not exist.

[libvirt] Virtual box storage and network sub-drivers
by Michal Privoznik 19 Aug '14

19 Aug '14

Dear list, Virtualbox driver has its own implementation of storage and network sub-drivers. But as of commit ba5f3c7c8ecc1037e44904916989a1c65777a9d5 (contained in the 1.0.6 release) when the VBox moved from client to daemon, the storage and network sub-drivers are indeed registered but in fact never called. It's due to our virConnectOpen function where the general network and storage drivers take precedence. So I guess my question is: should we drop the VBox sub-drivers or perhaps fix the virConnectOpen function? Reported-by: Taowei Luo Michal

Jim Fehlig (3): xen: rename xenxs to xenconfig src/xenconfig: remove dead code src/xenconfig: move common parsing/formatting to xen_common Kiarie Kahurani (2): src/xenconfig: wrap common parsing code src/xenconfig: wrap common formatting code cfg.mk | 2 +- configure.ac | 2 +- po/POTFILES.in | 5 +- src/Makefile.am | 39 +- src/{libvirt_xenxs.syms => libvirt_xenconfig.syms} | 4 +- src/{xenxs/xen_xm.c => xenconfig/xen_common.c} | 874 +++++++-------------- src/xenconfig/xen_common.h | 46 ++ src/{xenxs => xenconfig}/xen_sxpr.c | 2 +- src/{xenxs => xenconfig}/xen_sxpr.h | 0 src/xenconfig/xen_xm.c | 421 ++++++++++ src/{xenxs => xenconfig}/xen_xm.h | 0 src/{xenxs => xenconfig}/xenxs_private.h | 0 tests/sexpr2xmltest.c | 2 +- tests/xmconfigdata/test-escape-paths.cfg | 2 +- tests/xmconfigdata/test-fullvirt-force-hpet.cfg | 2 +- tests/xmconfigdata/test-fullvirt-force-nohpet.cfg | 2 +- tests/xmconfigdata/test-fullvirt-localtime.cfg | 2 +- tests/xmconfigdata/test-fullvirt-net-ioemu.cfg | 2 +- tests/xmconfigdata/test-fullvirt-net-netfront.cfg | 2 +- tests/xmconfigdata/test-fullvirt-new-cdrom.cfg | 2 +- tests/xmconfigdata/test-fullvirt-old-cdrom.cfg | 2 +- tests/xmconfigdata/test-fullvirt-parallel-tcp.cfg | 2 +- .../test-fullvirt-serial-dev-2-ports.cfg | 2 +- .../test-fullvirt-serial-dev-2nd-port.cfg | 2 +- tests/xmconfigdata/test-fullvirt-serial-file.cfg | 2 +- tests/xmconfigdata/test-fullvirt-serial-null.cfg | 2 +- tests/xmconfigdata/test-fullvirt-serial-pipe.cfg | 2 +- tests/xmconfigdata/test-fullvirt-serial-pty.cfg | 2 +- tests/xmconfigdata/test-fullvirt-serial-stdio.cfg | 2 +- .../test-fullvirt-serial-tcp-telnet.cfg | 2 +- tests/xmconfigdata/test-fullvirt-serial-tcp.cfg | 2 +- tests/xmconfigdata/test-fullvirt-serial-udp.cfg | 2 +- tests/xmconfigdata/test-fullvirt-serial-unix.cfg | 2 +- tests/xmconfigdata/test-fullvirt-sound.cfg | 2 +- tests/xmconfigdata/test-fullvirt-usbmouse.cfg | 2 +- tests/xmconfigdata/test-fullvirt-usbtablet.cfg | 2 +- tests/xmconfigdata/test-fullvirt-utc.cfg | 2 +- tests/xmconfigdata/test-no-source-cdrom.cfg | 2 +- tests/xmconfigdata/test-paravirt-net-e1000.cfg | 2 +- tests/xmconfigdata/test-paravirt-net-vifname.cfg | 2 +- .../test-paravirt-new-pvfb-vncdisplay.cfg | 2 +- tests/xmconfigdata/test-paravirt-new-pvfb.cfg | 2 +- .../test-paravirt-old-pvfb-vncdisplay.cfg | 2 +- tests/xmconfigdata/test-paravirt-old-pvfb.cfg | 2 +- tests/xmconfigdata/test-paravirt-vcpu.cfg | 2 +- tests/xmconfigdata/test-pci-devs.cfg | 2 +- tests/xmconfigtest.c | 2 +- tests/xml2sexprtest.c | 2 +- 48 files changed, 796 insertions(+), 671 deletions(-) rename src/{libvirt_xenxs.syms => libvirt_xenconfig.syms} (91%) rename src/{xenxs/xen_xm.c => xenconfig/xen_common.c} (72%) create mode 100644 src/xenconfig/xen_common.h rename src/{xenxs => xenconfig}/xen_sxpr.c (99%) rename src/{xenxs => xenconfig}/xen_sxpr.h (100%) create mode 100644 src/xenconfig/xen_xm.c rename src/{xenxs => xenconfig}/xen_xm.h (100%) rename src/{xenxs => xenconfig}/xenxs_private.h (100%) -- 1.8.4.5
