[libvirt] [test-API][PATCH] Fix problem in create netfs pool and logical volume
by Wayne Sun 29 Aug '12

29 Aug '12

create_netfs_pool: In rhel7 the source nfs mount dir shows in /proc/mounts will end with a '/' which in rhel6 and rhel5 didn't. So the check with exact match will fail on rhel7. Change with '/*' will accept with both '/' exist or not. create_logical_volume: When grep lvcreate command in /etc/lvm/backup/logical_pool for create logical volume, rhel6 and rhel7 command is slightly differnet with rhel5, so make the change to fit for all version.

[libvirt] Entering freeze for libvirt-0.10.0
by Daniel Veillard 29 Aug '12

29 Aug '12

As planned, I just tagged 0.10.0 release candidate 1 in git and pushed a tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I gave it a try locally and things seems to work as expected, but that's far from an extensive testing :-) So please try it, try to compile it on various platforms and send feedback to the list. My schedule is to make an rc2 probably for the week-end and ideally a final release a week from now, thanks in advance !

[libvirt] [PATCH 0/3] Fix bugs in DAC security driver preventing guest start
by Peter Krempa 29 Aug '12

29 Aug '12

When using the DAC security driver with security_default_confined = 0 the daemon segfaulted. After fixing that problem guests could not be started because the driver had a logic bug that used uninitialized values while setting hypervisor uid and gid. This is probably a regression and I would like to hear your opinion if it's worth to push before the release tomorrow.

[libvirt] make rpm does not work
by Gautam Sampathkumar 28 Aug '12

28 Aug '12

Hi All, I built libvirt on centos 6.2 and the configure and make steps went through successfully. I did try a make rpm which fails with the error: cp: cannot stat `./404.html': No such file or directory. Doesnt looks like any RPMs were generated. I tried to manually create 404.html in the current dir, but that didn't help. Any help or guidance would be much appreciated. thanks Gautam

[libvirt] libvirt-java, libvirt-client on Centos 6.2
by Gautam Sampathkumar 28 Aug '12

28 Aug '12

Hi All, I've been trying to upgrade our version of libvirt-java to 0.4.8 since we're now running libvirt 0.10.0 and are running into the following dependency problems on our Centos 6.2 machine. libvirt-java requires libvirt-client > 0.9.12 1. The libvirt-client RPMs all appear to be targeted to Fedora Core system and I'm not certain I should be trying to install these RPMs on my CentOS box. However, I'm unable to find a source tarball so I can build libvirt-client from source. 2. I did try to install the FC RPM libvirt-client-0.10.0-0rc0.fc16.x86_64.rpm and this fails with the error libc.so.6(GLIBC_2.14)(64bit) is needed by libvirt-client-0.10.0-0rc0.fc16.x86_64 libc.so.6(GLIBC_2.15)(64bit) is needed by libvirt-client-0.10.0-0rc0.fc16.x86_64 glib 2.12 is the latest version available via YUM for all CentOS 6.x distributions, so I attempted to build and install glibc 2.15 from source. I can confirm that we now have /usr/lib64/libc.so.6 installed. However, attempting to install libvirt-client still fails with the same error. 3. Not sure why libvirt-java depends on libvirt-client Any guidance or pointers would be much appreciated. thanks, Gautam

[libvirt] [PATCH] Don't require gawk for a simple print expression
