[libvirt] [PATCH] conf: RNG: Always fill in default random source path for default backend
by Peter Krempa 28 Jul '14

28 Jul '14

Libvirt documents that the default entropy source for the 'random' backend of a RNG device is /dev/random. Instead of storing and propagating NULL across our code and checking it in multiple places fill the default in the post parse callback and use that in the other places. --- Sending the fix as promised in the multiple-rng series. src/conf/domain_audit.c | 10 ++-------- src/conf/domain_conf.c | 14 +++++++++----- src/qemu/qemu_cgroup.c | 12 ++++-------- src/qemu/qemu_command.c | 5 ++--- .../qemuxml2argvdata/qemuxml2argv-virtio-rng-default.args | 2 +- .../qemuxml2argvdata/qemuxml2argv-virtio-rng-multiple.args | 3 ++- 6 files changed, 20 insertions(+), 26 deletions(-) diff --git a/src/conf/domain_audit.c b/src/conf/domain_audit.c index 2d1b1fb..93625fc 100644 --- a/src/conf/domain_audit.c +++ b/src/conf/domain_audit.c @@ -253,10 +253,7 @@ virDomainAuditRNG(virDomainObjPtr vm, if (newDef) { switch ((virDomainRNGBackend) newDef->backend) { case VIR_DOMAIN_RNG_BACKEND_RANDOM: - if (newDef->source.file) - newsrcpath = newDef->source.file;

[libvirt] default virtual network race with NetworkManager in a VM
by Cole Robinson 28 Jul '14

28 Jul '14

Hi all, There's a long standing issue with running libvirt inside a VM: https://bugzilla.redhat.com/show_bug.cgi?id=811967 Summary: Run a VM using the default virtual network with IP address 192.168.122.XXX. Install libvirtd inside the VM, reboot. On startup, libvirtd in the VM can bring up its copy of the default virtual network, before NetworkManager has a chance to run. The nested network grabs the route for 192.168.122.0 before NetworkManager can claim it for the VM's normal networking. Result is the VM doesn't have any network connectivity to the outside world. If NetworkManager starts first, a libvirt check at virtual network startup time will refuse to override the existing route and avoid the problem. This is from https://bugzilla.redhat.com/show_bug.cgi?id=235961 The past few Fedora releases haven't generated that many complaints about this, but we've had reports that it's happening quite frequently with rawhide/f21, see the last comments of that first bug report. There's some suggestions in the bug about possible fixes, like listening to NetworkManager API events and stopping the virtual network if needed. But they are just ideas that no one has really researched. Anyone have a novel solution and/or some cycles to poke at this? (FWIW no one has tried to determine what has changed that's tickling this issue more often, but regardless the root issue should be dealt with) Thanks, Cole

This sounds like a really cool feature that SUSE would probably be interested in extending back to 0.14 and 0.15, but I see a fundamental flaw: libvirt on those old source systems does not know it should use a different machine name on the destination side and would still use pc-1.0, wouldn't it? After all, it needs to be able to migrate to other old qemu-kvm machines, so it can't just be updated to use the new name. Minor bikeshedding: I would ask to keep the package name in front of the machine version, e.g. qemu-kvm-pc-1.0. Or just kvm-pc-1.0 since this is a QEMU parameter anyway. Haven't reviewed the code in detail yet. Regards, Andreas -- SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg
