Autodetecting backing file properties when using vol-create-as
Hi all, experimenting with vol-create-as, I think it should autodetect some data - filesize and backing file format, specifically. However, the current implementation require us to specify both filesize and backing file format. Considering that qemu-img already autodetects these data, there are any reason for the lack of autodetect by libvirt? Should I open a bugzilla issue? Below you can

Per-protocol ssl_protocols settings
Sorry for the bump... Anyone know if it is possible to have multiple protocols instances with different ssl_protocols settings? Regards.

ZFS on Linux repository
Hi list, we all know why ZFS is not included in RHEL/CentOS distributions: its CDDL license is/seems not compatible with GPL license. I'm not a layer, and I do not have any strong opinion on the matter. However, as a sysadmin, I found ZFS to be extremely useful, especially considering BTRFS sad state. I would *really* love to have ZFS on Linux more intergrated with current CentOS. From

Dovecot, pigeonhole and hardlinks
Hi list, many moons ago I asked about preserving hardlink between identical messages when pigeonhole (for sieve filtering) was used. The reply was that, while hardlink worked well for non-filtered messages, using pigeonhole broke the hardlink (ie: some message-specific data was appended to the actual mail file). Here you can find the original thread:

Per-protocol ssl_protocols settings
Hi all, I have a question regarding the "ssl_protocols" parameter. I understand that editing the 10-ssl.conf file I can set the ssl_protocols variable as required. At the same time, I can edit a single protocol file (eg: 20-pop3.conf) to set the ssl_protocols for a specific protocol/listener. I wander if (and how) I can create a different listener for another POP3 instance, for

Deleted symlinks when receiveing files with the same name
Hi list, I would like to know if the following rsync's behavior can be changed/modified. I noticed that when rsync receive a file for which the local filesystem already has a symlinks with the same path/name, it _first_ delete the symlink, _then_ it start the transfer. I think there are two problems with this approach: - it completely ignores the content of the symlinked files, which can

GlusterFS as virtual machine storage
Ciao Gionatan, I run Gluster 3.10.x (Replica 3 arbiter or 2 + 1 arbiter) to provide storage for oVirt 4.x and I have had no major issues so far. I have done online upgrades a couple of times, power losses, maintenance, etc with no issues. Overall, it is very resilient. Important thing to keep in mind is your network, I run the Gluster nodes on a redundant network using bonding mode 1 and I have

Windows guest skipping chkdsk if using Spice display
Hi all, as per subject, when a Windows guest using a Spice display is rebooted with a planned chkdsk, the consistency check is always skipped. It seems that the Spice display issues some "phantom" keystrokes, which are then intended by Windows as the "skip chkdsk at boot" signal. I tried to use a Spice display with no additional features (ie: USB redirection), but to no

GlusterFS as virtual machine storage
Solved as to 3.7.12. The only bug left is when adding new bricks to create a new replica set, now sure where we are now on that bug but that's not a common operation (well, at least for me).
