[libvirt] [PATCH] qemuProcessLaunch: Return earlier if spawning qemu failed
by Michal Privoznik 19 Jun '19

19 Jun '19

If spawning qemu fails then we report an error and proceed to writing status XML onto the disk. This is unnecessary as we are sure that the domain is not running. At the same time, if virPidFileReadPath() fails it returns -errno. Use it in the error message. It may explain what went wrong.

[libvirt] [PATCH] remote: delete the avahi mDNS support
by Daniel P. Berrangé 19 Jun '19

19 Jun '19

Libvirtd has long had integration with avahi for advertising libvirtd using mDNS when TCP/TLS listening is enabled. For a long time the virt-manager application had support for auto-detecting libvirtds on the local network using mDNS, but this was removed last year commit fc8f8d5d7e3ba80a0771df19cf20e84a05ed2422 Author: Cole Robinson <crobinso(a)redhat.com> Date: Sat Oct 6 20:55:31 2018 -0400 connect: Drop avahi support Libvirtd can advertise itself over avahi. The feature is disabled by default though and in practice I hear of no one actually using it and frankly I don't think it's all that useful The 'Open Connection' wizard has a disproportionate amount of code devoted to this feature, but I don't think it's useful or worth maintaining, so let's drop it I've never heard of any other applications having support for using mDNS to detect libvirtd instances. Though it is theoretically possible something exists out there, it is clearly going to be a niche use case in the virt ecosystem as a whole. By removing avahi integration we can cut down the dependancy chain for the basic libvirtd install and reduce our code maint burden. Signed-off-by: Daniel P.

This patch series introduces the following improvements to the testDomainInterfaceAddresses function: - if a dhcp range is defined for the network, addresses are returned from there (instead of hard-coded addresses that were returned before) - if the network is IPv6 even when a dhcp range is not defined IPv6 addresses will be returned instead of IPv4 - the @source argument is validated - only networks of type VIR_DOMAIN_NET_TYPE_NETWORK are considered Ilias Stamatis (3): test_driver: validate @source in testDomainInterfaceAddresses test_driver: return addresses only for nets of type network test_driver: consider DHCP ranges in testDomainInterfaceAddresses src/test/test_driver.c | 96 +++++++++++++++++++++++++++++++++++++----- 1 file changed, 86 insertions(+), 10 deletions(-) -- 2.22.0

[libvirt] [RFC PATCH] docs: Use our own implementation for fetching the RSS data
by Martin Kletzander 19 Jun '19

19 Jun '19

This is just a small script I wrote. It works the same way as all the libraries together which we are bundling, but with just JS. The only difference is that the day of the date is formatted as 2-digit, but this should be a bug in Firefox (at least locally for me) as the documentation states that type 'numeric' should actually not have leading zeros. It will not be executed when the page is loaded locally. It also uses the same proxy that query-rss uses. We can get rid of that, but we'd either need to have our own proxy, send a sss header to allow fetching the atom.xml or providing JSONP access to the RSS feed on virt-planet.

[libvirt] [PATCH] remote: drop code for migrating config files from pre-XDG dir layout
by Daniel P. Berrangé 19 Jun '19

19 Jun '19

The unprivileged libvirtd daemon switched to use the XDG dir layout in the 0.9.13 release, and included code for moving config files from the old location. The chances of someone upgrading libvirt from <= 0.9.12 directly to libvirt >= 5.5.0 is close enough to zero that we can reasonably drop the back compat code. Signed-off-by: Daniel P.
