[libvirt] [PATCH] qemu: Make sure permissions are set on VNC auto socket
by Cole Robinson 30 Apr '15

30 Apr '15

This can cause permissions failures if qemu.conf user/group is changed. Fix this by filling in the VNC auto socket path in the same code area that we fill in default listen address, ports, etc. https://bugzilla.redhat.com/show_bug.cgi?id=1151762 --- src/qemu/qemu_command.c | 10 ++-------- src/qemu/qemu_process.c | 11 ++++++++++- 2 files changed, 12 insertions(+), 9 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index ba15dc9..45fc63c 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -7544,7 +7544,6 @@ qemuBuildNumaArgStr(virQEMUDriverConfigPtr cfg, static int qemuBuildGraphicsVNCCommandLine(virQEMUDriverConfigPtr cfg, virCommandPtr cmd, - virDomainDefPtr def, virQEMUCapsPtr qemuCaps, virDomainGraphicsDefPtr graphics) { @@ -7561,12 +7560,7 @@ qemuBuildGraphicsVNCCommandLine(virQEMUDriverConfigPtr cfg, goto error; } - if (graphics->data.vnc.socket || cfg->vncAutoUnixSocket) { - if (!graphics->data.vnc.socket && - virAsprintf(&graphics->data.vnc.socket, - "%s/%s.vnc", cfg->libDir, def->name) == -1) - goto error; - + if (graphics->data.vnc.socket) { virBufferAsprintf(&opt, "unix:%s", graphics->data.vnc.socket); } else if (virQEMUCapsGet(qemuCaps, QEMU_CAPS_VNC_COLON)) { @@ -7944,7 +7938,7 @@ qemuBuildGraphicsCommandLine(virQEMUDriverConfigPtr cfg, break; case VIR_DOMAIN_GRAPHICS_TYPE_VNC: - return qemuBuildGraphicsVNCCommandLine(cfg, cmd, def, qemuCaps, graphics); + return qemuBuildGraphicsVNCCommandLine(cfg, cmd, qemuCaps, graphics); case VIR_DOMAIN_GRAPHICS_TYPE_SPICE: return qemuBuildGraphicsSPICECommandLine(cfg, cmd, qemuCaps, graphics); diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 605b3c6..5de46e2 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -4479,7 +4479,16 @@ int qemuProcessStart(virConnectPtr conn, goto cleanup; } - if (graphics->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC || + if (graphics->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC && + !graphics->data.vnc.socket && + cfg->vncAutoUnixSocket) { + if (virAsprintf(&graphics->data.vnc.socket, + "%s/%s.vnc", cfg->libDir, vm->def->name) < 0) + goto cleanup; + } + + if ((graphics->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC && + !graphics->data.vnc.socket) || graphics->type == VIR_DOMAIN_GRAPHICS_TYPE_SPICE) { if (graphics->nListens == 0) { if (VIR_EXPAND_N(graphics->listens, graphics->nListens, 1) < 0) -- 2.3.6

[libvirt] [PATCH v2] polkit: Allow password-less access for 'libvirtadm' group
by Cole Robinson 29 Apr '15

29 Apr '15

Many users, who admin their own machines, want to be able to access system libvirtd via tools like virt-manager without having to enter a root password. Just google 'virt-manager without password' and you'll find many hits. I've read at least 5 blog posts over the years describing slightly different ways of achieving this goal. Let's finally add official support for this. Install a polkit-1 rules file granting password-less auth for any user in the new 'libvirtadm' group. Create the group on RPM install https://bugzilla.redhat.com/show_bug.cgi?id=957300 --- v2: - Name the group libvirtadm (danpb) - Name the source file libvirt.rules and rename on install (eblake) daemon/Makefile.am | 13 +++++++++++++ daemon/libvirt.rules | 9 +++++++++ libvirt.spec.in | 15 +++++++++++++-- 3 files changed, 35 insertions(+), 2 deletions(-) create mode 100644 daemon/libvirt.rules diff --git a/daemon/Makefile.am b/daemon/Makefile.am index 300b9a5..974feed 100644 --- a/daemon/Makefile.am +++ b/daemon/Makefile.am @@ -53,6 +53,7 @@ EXTRA_DIST = \ libvirtd.init.in \ libvirtd.upstart \ libvirtd.policy.in \ + libvirt.rules \ libvirtd.sasl \ libvirtd.service.in \ libvirtd.socket.in \ @@ -233,6 +234,8 @@ policyauth = auth_admin_keep_session else !

[libvirt] [PATCH v2 0/7] Cleanup flags checking and fix setvcpus
by Pavel Hrdina 29 Apr '15

29 Apr '15

The first four patches only cleanup the flags checking in our APIs by introducing new macros to check exclusive flags and requirements. Patch 5/7 uses the new macros to do better flags checking for virDomainSetvcpusFlags API. Patch 6/7 introduces macro to check virsh options requirements. The last patch uses the requirement macro to cleanup virsh setvcpus code and fixes a bug with --maximum option. Because only the last patch actually fixes a bug issue, I'm not sure whether this patch series should wait for next release cycle.

[libvirt] [python PATCH] examples: Add example to make guest agent lifecycle event useful
by Peter Krempa 29 Apr '15

29 Apr '15

This example allows to use the guest agent event and metadata to track vCPU count set via the guest agent (agent-based onlining/offlining) and keep it persistent accross domain restarts. The daemon listens for the agent lifecycle event, and if it's received it looks into doman's metadata to see whether a desired count was set and issues the guest agent command. --- MANIFEST.in | 2 + examples/README | 2 + examples/guest-vcpus/guest-vcpu-daemon.py | 131 ++++++++++++++++++++++++++++++ examples/guest-vcpus/guest-vcpu.py | 76 +++++++++++++++++ 4 files changed, 211 insertions(+) create mode 100755 examples/guest-vcpus/guest-vcpu-daemon.py create mode 100755 examples/guest-vcpus/guest-vcpu.py diff --git a/MANIFEST.in b/MANIFEST.in index dd05221..2cd1b46 100644 --- a/MANIFEST.in +++ b/MANIFEST.in @@ -11,6 +11,8 @@ include examples/domsave.py include examples/domstart.py include examples/esxlist.py include examples/event-test.py +include examples/guest-vcpus/guest-vcpu-daemon.py +include examples/guest-vcpus/guest-vcpu.py include examples/topology.py include generator.py include libvirt-lxc-override-api.xml diff --git a/examples/README b/examples/README index 1d4b425..0cb4513 100644 --- a/examples/README +++ b/examples/README @@ -12,6 +12,8 @@ esxlist.py - list active domains of an VMware ESX host and print some info. also demonstrates how to use the libvirt.openAuth() method dhcpleases.py - list dhcp leases for a given virtual network domipaddrs.py - list IP addresses for guest domains +guest-vcpus - two helpers to make the guest agent event useful with agent based + vCPU state modification The XML files in this directory are examples of the XML format that libvirt expects, and will have to be adapted for your setup.

[libvirt] [PATCH 0/5] Use synchronous block job events in qemu_migration
by Michael Chapman 29 Apr '15

29 Apr '15

This patch series converts qemu_migration to use the synchronous block job event code introduced in commit 630ee5ac. It fixes two problems: - Drive mirroring has been broken since that commit, since the event indicating mirror readiness isn't processed while the VM object is locked. - Migration did not wait until the drive mirrors were properly cancelled, and this could cause disk corruption. Patch 1 moves qemuBlockJobEventProcess into a separate source file so it can be used by both qemu_driver and qemu_migration. Patch 2 introduces new qemuBlockJobSync* help functions to manage a synchronous block job. Patch 3 ensures that a thread waiting on a synchronous block job event is woken up should the domain crash. Patches 4 and 5 use the new synchronous block job helpers in qemu_driver and qemu_migration respectively.
