[libvirt] Pass additional environmental variables
by Sean Noonan 13 Aug '14

13 Aug '14

We're using sasl+gssapi+kerberos to do authentication for libvirt, including from hypervisor to hypervisor. However, the environmental variable filtering implemented in libvirt prevents this from working, so we're forced to run a locally patched version. Thoughts on the following patch to pass the location of the local credential cache as well? --- a/src/util/vircommand.c 2014-01-07 14:14:11.388934108 +0000 +++ b/src/util/vircommand.c 2014-01-07 14:18:14.725082505 +0000 @@ -1314,6 +1314,7 @@ virCommandAddEnvPair(cmd, "LC_ALL", "C"); + virCommandAddEnvPassBlockSUID(cmd, "KRB5CCNAME", NULL); virCommandAddEnvPassBlockSUID(cmd, "LD_PRELOAD", NULL); virCommandAddEnvPassBlockSUID(cmd, "LD_LIBRARY_PATH", NULL); virCommandAddEnvPassBlockSUID(cmd, "PATH", "/bin:/usr/bin");

[libvirt] [PATCH] qemu_conf: Undefine the correct symbol
by Michal Privoznik 12 Aug '14

12 Aug '14

At the beginning of the qemu config file parsing function there are 3 helper macros defined: GET_VALUE_BOOL, GET_VALUE_LONG and GET_VALUE_STR. Later, when they are no longer needed they are undefined in order to keep the namespace clean. However, the GET_VALUE_STRING is undefined instead of GET_VALUE_STR.

[libvirt] [PATCH v2] storage: ZFS support
by Roman Bogorodskiy 12 Aug '14

12 Aug '14

Changes from the initial version: - Update docs/schemas and docs/storage.html.in with ZFS backend information - Drop StartPool and StopPool that does nothing and therefore not needed - Fix memory leak in 'tokens' variable - Fill volume key before creating a volume - Use volume's target.path as a key - Allow not to specify 'target' for pool because in any case it should be /dev/zvol/$poolname Few notes on Linux support: I've been playing around with http://zfsonlinux.org/. I noticed it missed '-H' switch to provide a machine-friendly output and created a feature request: https://github.com/zfsonlinux/zfs/issues/2522 It was quickly fixed, so I've updated from the git version and moved on. >From that point it worked well and the only thing I had to modify is not to pass 'volmode' parameter during volume creation (it's freebsd specific and it could be e.g. just cdev or a FreeBSD geom provider). So, basically, for the current (limited) feature set the two things need to be checked on Linux: - zpool get support for -H switch - zfs volmode support for volume creation I'm open for suggestions what would be a good way to check it. For the '-H' thing, I was thinking about calling just 'zpool get -H' in StartPool. If the error says 'invalid option 'H'' (i.e. check if it just contains 'H'), then return an error that zfs version is too old. That's fragile, but probably less fragile than parsing usage that looks like that: usage: get [-pH] <"all" | property[,...]> <pool> ... As for the 'volmode', it's simple in terms of parsing, because e.g. 'zfs get' prints a nice set of parameters e.g.: volblocksize NO YES 512 to 128k, power of 2 volmode YES YES default | geom | dev | none volsize YES NO <size> So it should not be a problem to check it once and save in some sort of state struct inside of the ZFS backend.
