[libvirt] Change of server
by Daniel Veillard 27 Jun '14

27 Jun '14

I went ahead and switched earlier today, the new IP for libvirt.org is 91.121.203.120 , seems to me that all services are functionning as before, I also migrated the various cron. The DNS TTL should expire within 2 hours and everybody should see the new box then. it has twice the memory and twice the CPU power (still not a speed daemon by any measure but should be a bit better). Main point is that the hardware is newer and hence less likely to fail, but don't repeat it Murphy could hear about it !

[libvirt] [PATCH] test: add user_xattr check for securityselinuxlabeltest
by Jincheng Miao 26 Jun '14

26 Jun '14

libvirt unit test used setxattr with "user.libvirt.selinux" name to emulate setfilecon of selinux. But for some old kernel filesystem (like 2.6.32-431.el6.x86_64), if the filesystem is not mounted with user_xattr flag, the setxattr with "user.libvirt.selinux" will fail. So adding testUserXattrEnabled() in securityselinuxlabeltest.c, if user_xattr is not enabled, skip this case. The user_xattr is departed in newer kernel, therefore this commit is only for the compatablity for old kernel.

[libvirt] [for 1.2.6] Redundancy of virNetworkGetDHCPLeases and virNetworkGetDHCPLeasesForMAC
by Peter Krempa 26 Jun '14

26 Jun '14

Hi, when reviewing the patch to add python bindings for the said APIs it occurred to me that the two APIs are so close in their prototypes and way of functioning that we could actually merge them into one. Both of those return a list of lease structures and the only difference is the presence of the @mac argument. We could unify those two APIs into one with the following signature: int virNetworkGetDHCPLeases(virNetworkPtr network, const char *mac, virNetworkDHCPLeasePtr **leases, unsigned int flags) And tweak the semantics of @mac where when the user passes NULL we'd return the complete unfiltered list. This would simplify our API and also the python bindings. If we decide this is a good idea (in time for the release) I'll post patches to flesh out the redundant parts. Peter

[libvirt] [PATCH] qemu: fix guestfwd chardev option back how it was
by Martin Kletzander 26 Jun '14

26 Jun '14

Since commit d86c876a66e320b55220d00113027c9ad6199cff we are using guestfwd=tcp:IP:PORT,chardev=ID for guestfwd specification, however, that has not changed in qemu, so guestfwd does not work since. Apart from that, guestfwd is not working with older qemu that doesn't have QEMU_CAPS_DEVICE. Both regressions exist since late 2009 and nobody found that (until now), so I'm only fixing the first one.

[libvirt] [PATCH] docs: publish correct enum values
by Eric Blake 26 Jun '14

26 Jun '14

We publish libvirt-api.xml for others to use, and in fact, the libvirt-python bindings use it to generate enum values. However, we had an off-by-one bug that any enum that relied on C's rules for implicit initialization of the first enum member to 0 got listed in the xml as having a value of 1 (and all later members of the enum were equally botched). Affected are: - virDomainCoreDumpFormat (such as VIR_DOMAIN_CORE_DUMP_FORMAT_RAW), since libvirt TBD - virDomainEventGraphicsAddressType (such as VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV4), since libvirt TBD - virIPAddrType (such as VIR_IP_ADDR_TYPE_IPV4), since libvirt TBD The fix is simple - since we add one to the previous value when encountering an enum without an initializer, the previous value must start at -1 so that the first enum member is assigned 0. Thanks to Nehal J Wani for reporting the problem on IRC, and for helping me zero in on the culprit function. * docs/apibuild.py (CParser.parseEnumBlock): Fix implicit enum values.

[libvirt] [PATCH] Fix typo s/SASL_CONF_DIR/SASL_CONF_PATH/ in QEMU VNC code
