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

To me, this seems a _very_ important feature, and I wonder if I am doing something wrong or if the feature (hardlink+sieve) simply does not exists. Hardlink+Sieve has never worked. The fix is a bit complicated. Here's my

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

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

I have a system with two CentOS 7.1 guests. When I created the VMs I did not have enough storage space in the default location /var/lib/libvirt/images so I moved the default location to a directory /home/vmimages. While this configuration is functional I regret creating a new storage pool in /home. I would like to create a separate partition to place the VM images removing them from their

Hi Javier, thanks for your reply. I already checked SIS and, while interesting, is not what I want, because: 1) it can be difficult to restore a single message/attachment from a backup 2) only the attachments, and not the entire messages, are deduped. Message-based hardlinks really exists for a reason. The good news is that I found _why_ they are not working: it depends from how dovecot and

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:

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

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

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

Hi, Thanks Kashyap for your answer.

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
