    Can hosts in a cluster run over a non-standard SSH port (i.e. not 22)

    Nice one Dietmar - indeed. You need to change the port in both /etc/ssh/ssh_config and /etc/ssh/sshd_config.

    How to speed up restore to LVM over LUN over SAN

    Hi all, This might not be possible (because of the block level of the restore) but is there anyway to speed up restores to a LUN on a SAN? If I backup a relative empty 5GB VM on a SAN I get a 700MB .tar file. However, when I restore it to the SAN it writes all 5GB (doing dd I expect)...

    How to resize LUN from SAN?

    Hi all, I have successfully hooked up Proxmox to my SAN (recent forum posts not withstanding ;)) but now I want to resize the LUN. I have resized it on the SAN - what do I need to do on Proxmox?

    Feature request - display the machine name next to the KVM nodeID on the VM' web page

    Hi, If I click on a VM I get into the "Virtual Machine Configuration" section. It would be really nice if as well as displaying the "KVM nodeId" it also displayed the hostname. For example, rather than "KVM 101" it displayed "(KVM 101) my-machine.name". Nobody cares about the vmID :)

    Feature request - display a drop down of all the VMs on the /qemu/X/*.htm pages

    Hi, I quite often want to do something to a lot of machines. When I click into a VM I can see a lot about it, status, hardware, options and monitor. It would be handy if there was a drop down somewhere on each of those pages which listed all the VMs so I could conveniently jump to another VM.

    What network monitor system do you use?

    Just to reply to an old thread I started - I have actually gotten into zabbix. It is really very nice - it gives you *loads* of out of the box reporting without you having to do anything. It is very open and extensible, but comes pre-configured with lots of very nice templates...

    Disks have disappeared from the SAN(!)

    (URGENT!!) Disks have disappeared from the SAN Hi all, Has anyone experienced SAN backed disks just disappearing? Yesterday I created about 40 small VMs whose disks were backed by a SAN. Everything was fine until I apt-get update ; apt-get dist-upgrade this morning and then rebooted...

    Can I have a cluster where some nodes can see the SAN but others cannot?

    Ah ok - I think I will leave it out then. Better safe than sorry.

    Proxmox 2.x planned features

    Regarding the actual configuration and management of the machines, I would strongly recommend puppet (http://www.puppetlabs.com/). You basically define each host (or classes of host) and say things like "hostA is a web server so it should have apache and this SSL key and the nagios checks are...

    Cluster SAN Problems

    First - I have a similar setup, 3 servers with dual 1GB dedicated NICs to a HP SAN (which has 4 1GB NICs altogether). (KVM) VMs on the cluster all work fine, but aren't exactly leaving blazing tyre tracks in their wake: qfiadmin@wiki:~$ time `dd if=/dev/zero of=/tmp/2G bs=1M count=2048...

    Can I have a cluster where some nodes can see the SAN but others cannot?

    Hi all, I have 4 machines - three of which have NICs to the SAN but the other one doesn't (it has local storage). Is it safe to add the SAN-less one into the cluster? Will the fact it has different networking (it is still the same network) break things? Thanks, Col

    Is it safe to have more VMs than cores when using KVM?

    Thought so - just wanted to check. Thanks Udo.

    Is it safe to have more VMs than cores when using KVM?

    Hi all, Googling turned up yes and no ;). I have a dual Xeon server which, with hyper threading gives 16 cores. I have plenty of CPU "power" and memory to do what I want, but I prefer to have lots of little VMs rather than fewer monolithic VMs. So, how many VMs should I aim to put onto...

    Feature request - allow cluster communication over non-standard SSH ports

    It seems that changing the SSH ports to something other than 22 breaks communication in the cluster. Steps to reproduce: - change /etc/ssh/sshd_config so Port is something other than 22 (i.e. 222) - reboot - watch the synchronisation errors on the main page

    Can hosts in a cluster run over a non-standard SSH port (i.e. not 22)

    Hmm, it appears it cannot - I edited both /etc/ssh/sshd_config to port 222, rebooted and then watched lost of synchronisation errors because the machines couldn't connect to localhost 10050 (or something like that). Changing back to 22 works fine.

    Some ideas for the Roadmap

    Even if snapshotting the entire VM is dangerous it would be convenient to be able to define templates that default values for the 'create' page. For example, I find myself creating lots and lots of Ubuntu 10.4 KVM machines with 8GB of disk, 512 of RAM, the same vmbrX and attached to the install...

    Which kernel to use for KVM only production server running DBServers?

    Hi all, I am running 2.18 as installed by the ISO CD but I am wondering whether I should upgrade to .32 as I am only using KVM. I don't really need the memory ballooning, I am primarily concerned with stability and disk IO speed. Should I stay on 2.18 for stability? Thoughts?
