ok, thanks. Supermicro website is kind of a mess but I will find my way through it, I guess. Another thing that I didn´t list is a fibre channel or infiniband switch for ceph. For start I could also imagine a Mesh network like described here...

I like the linked Controller! Also the other hints are very useful. What about the 2U case? can you recommend any manufacturer? Talking about high frequency CPU: can you recommend an up-to-date and affordable Xeon for this purpose? Besides Ceph I also want to run the VM machines on this...

Hello, can anyone recommend some manufacturers for building a professional selfmade server? It would be nice if some concrete products would be named for following pieces: Case (2U Rackmount, 24x2,5", redundant Power supply) Mainboard (Intel Xeon Processor, min. 2 Sockets, IPMI, min. 2 NIC)...

Hello, what would be the correct setup if I want to have all KVM-machines to have the same time? Might it be necessary to separately install ntp on all KVM-machines? I tried "Use local time" but the result is not correct. Maybe because I have configured a timezone with tzdata? Regards, Afox

hello, for me this error did not show up for a long time now. I also checked system time and saw nothing remarkable. I thought they fixed it in an update. If your system is not up to date, maybe updating can fix the issue. Regards, Afox

Hello, if you had unlimited ressources, what would be the ideal setup for a high performance LAMP server cluster that could require a lot of storage capacity? You can also expect a lot of PHP/mysql work. Questions I have: what storage should be used? If you have e.g. one node running a load...

nobody? this problem seems to be random. I don´t get it.

Hello, I get this error when triggering SPICE Session via webinterface. Interesting is: It´s not for all VMs, only 2. Machines are KVM, qxl driver is selected. I use virt-viewer on Linux. Any idea to solve this? What password is needed here? Regards, Afox

could there be a solution in building an OVS bridge and adding an OVS IntPort to the node? And then adding all the VMs to the bridged OVS network? Edit: I answer myself: yes, this works!

hi, thanks for your reply. Copying between 2 VMs is working well and with no outgoing traffic. But I can´t manage to access the node itself from a VM/LXC without going over the hardware-switch which means traffic goes from VM to Switch and then to Node. It worked with Proxmox 3 where I...

Hello, is there any minimal LXC Template for Debian 8? I only found the "standard" version. I am not sure if this is minimal (without webserver etc.). Regards, Afox

Hello, I found that if I address the public IP of an OpenVZ container from another OpenVZ container, there is no outgoing traffic (which is exactly what I want) and routing is made internally. Before I migrate to KVM, will this also work with KVM-machines? Also I only tested with containers...

Hello, how to change my root password for Proxmox? I remember the old password and just want to change it. Is it possible to just change it with passwd Or do I have to go the way described in this article: https://pve.proxmox.com/wiki/Debian_reset_root_password Regards, Afox

hello, thanks for your answer. If you keep the beta-stadium aside, is DRBD9 expected to be "faster" (better IOPS, response time etc.) than CEPH? theoretically, what are the pros and cons (i can wait a little for stable release).

Hello, if you could choose between DRBD9 and CEPH, what would be your favorite and why? Lets say buying a RAID-Controller would not be a problem and it is all about performance (e.g. response time) and scalability. Thanks in advance, Afox

i know, this is no problem in my scenario.

is it possible to predefine all the data and just open virt-viewer by running this script without any further commandline-interaction (one example would help me a lot)? can a regular user run this script on a unix-machine without entering root password?

hello, i linked it above: https://git.proxmox.com/?p=pve-manager.git;a=blob_plain;f=spice-example-sh;hb=HEAD

Hello, I want to use this script to call SPICE sessions. I don´t have any experience with such scripts and need to ask a newbie question: where do I put my user-data in this script? Is it possible to run this script as a regular "user" or do I need sudo/root privileges? Thanks for any helpful...

You Sir, just posted the solution! thank you so much!
