[libvirt] [PATCH 00/68] qemu: Refactor migration parameters
by Jiri Denemark 06 Apr '18

06 Apr '18

This series changes the way we handle migration parameters and capabilities with several goals: - make it all consistent and avoid storing the same parameters in several structs - reduce the number of QMP commands we use for setting migration capabilities - concentrate the logic in a separate file and make the code for migration parameters and capabilities in qemu_migration.c less complicated - reset all parameters and capabilities at the end of migration - make adding new parameters and capabilities easier Jiri Denemark (68): qemu: Move qemuDomainCheckMigrationCapabilities qemu: Rename

[libvirt] [PATCH 0/7] Prepare for daemon split
by Daniel P. Berrangé 06 Apr '18

06 Apr '18

When we split up the daemons, libvirtd will need to forward different sets of APIs to different daemons. This means libvirtd is going to need to have multiple virConnectPtr instances open. This series prepares for that by introducing "separate" connections, which are actually just an extra reference on the current single connection. This will facilitate later changes. Daniel P. Berrangé (7): rpc: refactor way connection object is generated for remote dispatch remote: use a separate connection for interface APIs remote: use a separate connection for network APIs remote: use a separate connection for nodedev APIs remote: use a separate connection for nwfilter APIs remote: use a separate connection for secret APIs remote: use a separate connection for storage APIs src/remote/remote_daemon.h | 6 +++ src/remote/remote_daemon_dispatch.c | 81 +++++++++++++++++++------------ src/rpc/gendispatch.pl | 95 ++++++++++++++++++++++++++++--------- 3 files changed, 128 insertions(+), 54 deletions(-) -- 2.14.3

[libvirt] anyone ever seen virDomainCreateWithFlags() essentially hang?
by Chris Friesen 05 Apr '18

05 Apr '18

I'm investigating something weird with libvirt 1.2.17 and qemu 2.3.0. I'm using the python bindings, and I seem to have a case where libvirtmod.virDomainCreateWithFlags() hung rather than returned. Then, about 15min later a subsequent call to libvirtmod.virDomainDestroy() from a different eventlet within the same process seems to have "unblocked" the original creation call, which raised an exception and an error code of libvirt.VIR_ERR_INTERNAL_ERROR. The virDomainDestroy() call came back with an error of "Requested operation is not valid: domain is not running". The corresponding qemu logs show the guest starting up and then a bit over 15min later there is a "shutting down" log. At shutdown time the libvirtd log shows "qemuMonitorIORead:609 : Unable to read from monitor: Connection reset by peer". The parent function did two additional retries, and both the retries failed in similar fashion. In all three caess there seems to be a pattern of the qemu instance starting up but virDomainCreateWithFlags() not returning, then a subsequent virDomainDestroy() call for the same domain causing the virDomainCreateWithFlags() call to get "unblocked" and return -1 leading to an exception in the python code. Any ideas what might cause this behaviour? I haven't reproduced the "hanging" behaviour myself, I'm working entirely off of logs from the affected system. Thanks, Chris

[libvirt] Run libvirtd from git: virsh hangs
by Mathieu Tarral 05 Apr '18

05 Apr '18

Hi, I managed to compile libvirt from the git repo, now i have some trouble to run it. This is what i did: I configured the source to use /var because i wanted the socket to be at the same place as the system one (/var/run/libvirt/libvirt-sock) ./configure --prefix=$HOME/usr --localstatedir=/var make make install at this point i stopped my system libvirtd and virtlogd sudo systemctl stop libvirtd sudo systemctl stop virtlogd And then i launched my custom libvirtd and virtlogd cd $HOME/usr/sbin sudo ./libvirtd -v sudo ./virtlogd -v After that i tried to list the available domains with virsh (using the system binary) sudo virsh virsh # list --all And this call hangs forever. There is no more output in libvirtd stdout/stderr, even if i set log_level to 1. Did i miss anything in the configuration ? Thanks guys ! -- Mathieu Tarral
