[libvirt] [PATCH] Mark internal.h for translation
by Jiri Denemark 16 Apr '10

16 Apr '10

Patch for virCheckFlags added a message marked for translation into internal.h without including that file in POTFILES.in. I've just pushed the following patch.

[libvirt] unable to set security context (NFSv4 problem?)
by Harald Dunkel 16 Apr '10

16 Apr '10

Hi folks, Since I have moved the image file of a domain to an NFS partition I get an error message at start time: # virsh start mydomain error: Failed to start domain mydomain error: unable to set security context '110:140' on '/storage/mydomain/vda.img': Invalid argument The /storage partition is mounted with these options: # cat /proc/mounts | grep /storage nasl002:/storage/ /storage nfs4 rw,relatime,vers=4,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=172.19.96.31,addr=172.19.96.213 0 0 If I use a local disk instead, then there is no such problem. libvirt is version 0.7.7-4, as included with Debian. Any helpful comment would be highly appreciated. Regards Harri

[libvirt] [PATCH v2 0/2] Enhance checking of supported flags in drivers
by Jiri Denemark 16 Apr '10

16 Apr '10

I think we need a simple and consistent way of checking whether flags passed to API entry points in drivers are valid/supported or not. So far some entry points don't check flags at all and some checks for 0 when no flags are expected/supported. The first patch introduces a macro which can be called with a whitelist of supported flags (more info about it inside the patch). The second patch changes all API calls introduced in 0.8.0 release to use the macro for checking valid flags. I'm not sure if we can change existing API calls to do the same as it could break some badly written apps which pass invalid flags. My opinion is that we may often do that as such apps don't use the API in a documented/valid way. Changes in v2: - virCheckFlags moved from checks.h to existing internal.h Jirka Jiri Denemark (2): Introduce virCheckFlags for consistent flags checking Use virCheckFlags for APIs added in 0.8.0 src/esx/esx_driver.c | 43 ++++++++++++------------- src/internal.h | 23 +++++++++++++ src/nwfilter/nwfilter_driver.c | 4 ++- src/qemu/qemu_driver.c | 68 +++++++++++++++++++--------------------- src/storage/storage_driver.c | 6 +--- src/vbox/vbox_tmpl.c | 41 ++++++++++++++++------- src/xen/xend_internal.c | 4 ++ 7 files changed, 111 insertions(+), 78 deletions(-)
