[libvirt] access with VNC and graphic interface
by Kenneth Nagin 28 Mar '11

28 Mar '11

libvirt provides vnc to access the VMs under its control. However, I can not get applications with graphical interface to run when I use vnc to access a VM. The same applications will display properly if I ssh -X to the VM. Is there anyway to overcome this problem? Best Regards, Kenneth Nagin

[libvirt] [PATCH] Reserve first 3 PCI slots for hardcoded devices
by Philipp Hahn 28 Mar '11

28 Mar '11

If a domain is initially created without a <vidoe> device but with other devices (like <interface>), PCI device slots normally reserved for hardcoded devices (host bridge, IDE controller, video) get assigned to these. If than later on a <video> device is added without removing the already assigned <addresse>s, the re-definition fails in qemuAssignDevicePCISlots() with the error message "Primary video card must have PCI address 0:0:2.0" To simplify editing existing domains just reserve the first three slots for internal usage by setting qemuDomainPCIAddressSet.nextslot = 3.

[libvirt] [PATCH RFC] Remove the Open Nebula driver
by Daniel P. Berrange 28 Mar '11

28 Mar '11

The Open Nebula driver has been unmaintained since it was first introduced. The only commits have been for tree-wide cleanups. It also has a major design flaw, in that it only knows about guests that it has created itself, which makes it of very limited use. Discussions wrt evolution of the VMWare ESX driver, concluded that it should limit itself to single-node ESX operation and not try to manage the multi-node architecture of VirtualCenter. Open Nebula is a cluster like Virtual Center, not a single node system, so reasoning applies. The DeltaCloud project includes an Open Nebula driver and is a much better fit architecturally, since it is explicitly targetting the distributed multihost cluster scenario. Thus this patch deletes the libvirt Open Nebula driver with the recommendation that people use DeltaCloud for managing it instead. * configure.ac: Remove probe for xmlrpc & --with-one arg * daemon/Makefile.am, daemon/libvirtd.c, src/Makefile.am: Remove ONE driver build * src/opennebula/one_client.c, src/opennebula/one_client.h, src/opennebula/one_conf.c, src/opennebula/one_conf.h, src/opennebula/one_driver.c, src/opennebula/one_driver.c: Delete files * autobuild.sh, libvirt.spec.in, mingw32-libvirt.spec.in: Remove build rules for Open Nebula * docs/drivers.html.in, docs/sitemap.html.in: Remove reference to OpenNebula * docs/drvone.html.in: Delete file --- autobuild.sh | 1 - configure.ac | 41 -- daemon/Makefile.am | 4 - daemon/libvirtd.c | 7 - docs/drivers.html.in | 1 - docs/drvone.html.in | 108 ------ docs/sitemap.html.in | 4 - libvirt.spec.in | 12 +- mingw32-libvirt.spec.in | 1 - src/Makefile.am | 29 -- src/README | 5 +- src/opennebula/one_client.c | 207 ----------- src/opennebula/one_client.h | 62 ---- src/opennebula/one_conf.c | 285 --------------- src/opennebula/one_conf.h | 54 --- src/opennebula/one_driver.c | 850 ------------------------------------------- src/opennebula/one_driver.h | 30 -- 17 files changed, 3 insertions(+), 1698 deletions(-) delete mode 100644 docs/drvone.html.in delete mode 100644 src/opennebula/one_client.c delete mode 100644 src/opennebula/one_client.h delete mode 100644 src/opennebula/one_conf.c delete mode 100644 src/opennebula/one_conf.h delete mode 100644 src/opennebula/one_driver.c delete mode 100644 src/opennebula/one_driver.h diff --git a/autobuild.sh b/autobuild.sh index 54fb273..491f1b8 100755 --- a/autobuild.sh +++ b/autobuild.sh @@ -81,7 +81,6 @@ if [ -x /usr/bin/i686-pc-mingw32-gcc ];

[libvirt] [RFC: PATCHv4 00/15] outgoing migration via fd: rather than exec:
by Eric Blake 27 Mar '11

27 Mar '11

v3 has not had complete reviews yet, located at: https://www.redhat.com/archives/libvir-list/2011-March/msg00132.html I'm posting v4 rebased on the latest tree, to get more feedback and possibly ACKs for the earlier half of the series. Differences in v4 (still incomplete): rearrange some of the earlier patches, incorporate Paolo's feedback Currently well-tested through patch 11. Remaining patches (12-15) are compiling but not yet tested, but should form the basis for doing compressed migration. Also available via: git fetch git://repo.or.cz/libvirt/ericb.git fd-migration Still to go - I really hate that doCoreDump can't use fd-migration until I make it compute qemuCaps; really, we should be computing caps once at vm startup, and remembering it elsewhere doCoreDump only works to regular files and fails on root-squash NFS, it should be possible to fix that I really need to write virCommandKill, which silently kills an async child process (if one is running) without overwriting any error messages Needs more testing - especially on root-squash NFS Eric Blake (15): qemu: use lighter-weight fd:n on incoming tunneled migration qemu: consolidate duplicated monitor migration code qemu: improve efficiency of dd during snapshots qemu: support migration to fd util: use SCM_RIGHTS in virFileOperation when needed qemu: allow simple domain save to use fd: protocol qemu: simplify domain save fd handling storage: simplify fd handling util: rename virFileOperation to virFileOpenAs util: adjust indentation in previous patch qemu, storage: improve type safety qemu: use common API for reading difficult files qemu: consolidate migration to file code qemu: skip granting access during fd migration qemu: support fd: migration with compression src/libvirt_private.syms | 2 +- src/qemu/qemu_driver.c | 626 ++++++++++++++++------------------------- src/qemu/qemu_migration.c | 45 +-- src/qemu/qemu_monitor.c | 124 ++++++++- src/qemu/qemu_monitor.h | 4 + src/qemu/qemu_monitor_json.c | 125 +-------- src/qemu/qemu_monitor_json.h | 23 +-- src/qemu/qemu_monitor_text.c | 123 +-------- src/qemu/qemu_monitor_text.h | 23 +-- src/storage/storage_backend.c | 80 +++--- src/util/util.c | 161 ++++++++---- src/util/util.h | 15 +- 12 files changed, 544 insertions(+), 807 deletions(-) -- 1.7.4
