this is another possible angle to tackle this: http://openvz.org/Vzmigrate_filesystem_aware if you have shared storage this will make vzmigrate skip the rsync completely and only transfer the memory content of the container. Does MariaDB cause this issue too by the way? thats a mysql fork...

I just made another post (just above yours). also by "suspend" I actually meant /etc/init.d/mysql stop. You'd need to do that after the first rsync pass to minimize mysql downtime

Or heres an alternative idea: You really only ever need 1 mysql server per openVZ host since you can just share the socket across all the containers. Knowing that you can have a mysql container on each node and just keep the databases synced up in some way (clustering, replication...

This is probably not what you'd want to hear but: I just don't. However if I did have to tackle that, I would probably go implement a workaround for mysql's weird io handling. Meaning: modify vzmigrate to suspend mysqld during live migrations (its just a shell/perl script after all). I have even...

This is not fair. You make it sound like the community (aka EVERYBODY) would want ploop, which is just not true. ploop is a feature that could be nice to have (as in: gimicky), but its really not as essential as you make it sound. also: You might want to contact the proxmox team via email...

doing a debian into proxmox installation should definitely allow you to put the root partition onto ZFS. you can even find guides for that like (randomly picked search result): https://github.com/zfsonlinux/pkg-zfs/wiki/HOWTO-install-Debian-GNU-Linux-to-a-Native-ZFS-Root-Filesystem

ceph is a storage CLUSTERING solution. You can add any number of disks on any number of machines into one big storage cluster. Then you set up the configuration for ceph, most notably the number of copies of a file. If you set this to 2 for instance, it means that the cluster will always have 3...

Yes, since that cpu has AMD-V (the intel VT counterpart). Not that I would ever recommend ESXi, but apparantly ESXi does run on AMD-V cpus, even though its not listed in the vmware compatibility list. Meaning for a testlab this should be fine. You can do this with openvz containers (which are...

All this mentions is the usage of rsync in a way where you have the receiving end also run an rsync demon that accepts connections. This is because the problem mainly boils down to network basics: If you want to connect from Host A to Host B to transfer a file, you need a listening service on...

I would even go so far as to say that this is probably a redmine problem. You would most likely have to take it up with them also: via http://stackoverflow.com/questions/18645070/how-to-move-redmine-to-a-sub-uri-with-nginx-as-a-proxy

while we're at it, this is how my lighttpd proxy looks like: server.modules += ( "mod_proxy" ) server.bind = "0.0.0.0" $SERVER["socket"] == "[::]:443" { server.use-ipv6="enable" } $SERVER["socket"] == "[::]:80" { server.use-ipv6="enable" } $SERVER["socket"] == "0.0.0.0:443" {...

As far as Im aware: unless you want to implement modifications to vzmigrate as demonstrated here: http://openvz.org/Vzmigrate_filesystem_aware (Note: I don't know whether the linked code is still being maintained), you HAVE to use NFS for openvz shared storage. So. you could either have a NFS...

I don't know redmine nor nginx, but having a specific error message is always a great angle for further research on the internet

this sounds like youre talking about webservers. in that case you need a CT that listens on port 80 of whatever IP all these domains point to. you'll need to route the traffic to that container via iptables. on this container you want a http proxy. both lighttpd and apache2 can do this. This...

looks like this ovs thing is basically just a wrapper for iptables/brutils/wondershaper. Or did I miss anything?

While I am not a developer and cant speak for proxmox to answer your question directly, I will say that I just took a look and havent found anything that would indicate active development of RHEL7 patches quite yet. That doesnt mean theres no development going on, just means its very well hidden ;)

Im afraid it comes down to this: every single VNC or KVM system out there has at least one situation where it wont let you send a seemingly "normal" keypress, often depending on client and server keyboard layout. Hell even HP's virtual console has lots of keys that are broken... As m.ardito...

hm. yes apparently youre right. however, openvz has more recent templates, such as: download.openvz.org/.../centos-6-x86_64.tar.gz this template is dated 2014-01-17 01:23:17 215 Mb, so... very much recent (meaning it should be 6.5... I hope). And while it does not say minimal, the "normal"...

as far as KVM is concerned, its explained in the wiki: http://pve.proxmox.com/wiki/VM_Templates_and_Clones I wouldn't recommend converting a KVM template into an openvz template because this most likely leaves the openvz template MUCH bigger than it actually needs to be if properly set up...

I noticed how firefox says that it has blocked mixed content from this site, which makes me think that the WYSIWYG editor may be partly delivered over http
