That's how you host is suppsed to behave. Take a look here: http://www.linuxatemyram.com/

OK. Have fun anyway :-)

Enjoy. BTW, what sort of environment are you going to use on that glusterfs setup? I'd like to run a Windows 2012 VM with a pretty heavily loaded MS SQL DB which may result in some race conditions and is not recommended to be used on top of GlusterFS, but I'd like to find out if that's actually...

I haven't found any official guides, but you can try this one: http://blog.ivanilves.com/2014/proxmox-ve-3-3-2-node-cluster-with-glusterfs/

Hi, We're preparing a migration scenario where we'd like upgrade our Proxmox 3.4 cluster to 4.x and convert our exisitng storage to SSD. Would you consider it smart enough to put DRBD9 based volume over mdadm RAID-10 over a set of SSD storage? AFAIK, SSDs themselves should be able to provide...

It's being worked on. Keep an eye on this thread: http://thread.gmane.org/gmane.comp.emulators.qemu/387810

I don't think that third node is required for DRBD9 itself. From what I know, it's purpose is to make HA work and provide quorum for the failed-node-detection mechanism to function properly. What I'm more intrested in is DRDB9's production environment readiness, general stability and...

Hi. Would you guys consider DRBD9 with PVE 4.1 stable enough for a production ready solution with a two-node (no HA for now) setup hosting an email apliance storing few hundred GBs of data? Or would it be better to stick to 3.4 until DRBD9 matures? And if I go with 3.4 will it be enough deploy...

There are other solutions that while not as felxible as Proxmox (I admit) are still able to run a two-node cluster. You could even get a two-node-no-external-storage with XenServer and some 3rd party additions and that's a scenario we're currently considering as our just in case Proxmox...

Too bad. Being able to run a HA cluster in such configuration was a great feature. Does it mean that Proxmox will require at least three servers + shared storage to run in high avaibility setup from now on?

Hi,Are there any plans to add qdisk support for two-node HA in future Proxmox 4.0 builds?We're running a three servers setup where one of them acts as an NFS storage and /qdisk member and we'd love to stick with this easy-to-maintain setup.

Thanks for the explanation.So if I want to add more CPU to an online guest the best way is to add cores instead sockets, but what's the right way to make the guest become aware of NUMA?My current setup is a Windows 2012 VM configured with one socket containing six cores and there seems to be no...

Hi,We have a dual socket Xeon E5-2620v2 based server running proxmox 3.4-6 with HT, 12 cores, 24 threads max, it has a NUMA enabled BIOS.I'd like to know if we should enable NUMA for each of our guest VMs (three W2012R2s running SQL Server 2008/AD controller/IIS Server) as well? Will it improve...

Hi, We've been having some serious connection issues with our two node proxmox cluster while they were connected using 10Gb SFP link, so we decided to get a separated (direct) 1gbit RJ45 connection for the nodes to communicate and leave that 10gbit link exclusively for the shared storage NFS...

Hello again, We've added an additional 1Gbit network card to our storage server to create another bridge and connected NODE1 and NODE2 to it. The nodes are now connected to the storage via two links - 1Gbit used for quorum and inter-node connectivity plus 10Gbit for NFS access. We ran manual...

Hi, We've recently configured a Proxmox node with two hosts and shared storage. All three servers are connected directly via 10Gbit Intel 82599EB based SFP+ link. Storage server runs on latest OpenMediavault and provides 32TB of RAID10 (mdadm based) space for both backups, ISOs and VMs over NFS...

Hmmm... That CPU usage seems really weird. I'm copying a database from our main SQL server to that Windows 2012 guest and right now Windows' task manager shows ~8% CPU being used, while host's CPU usage from top floats around 30% but dstat gives me this: ----total-cpu-usage---- -dsk/total-...

I guess yes. If that'd that let me add for example hv_time to -cpu switch. Would it?

We've already enabled that flag. Our current dstat int/csw results are: ---system-- int csw 1228 9229 368 1684 407 1724 365 1727 402 1732 734 1976 1144 3065 392 1732 892 2789 672 1773 1514 3646 405 1924 376 1719 415 1776 442 1935 494 1857 1071 3099 544 1956...

Thanks for you swift reply. We're not using memory ballooning on this VM and the PCI device itself has been disabled. Adding hv_time doesn't seem to work with current kernel (doesn't make any difference) and we'd rather stay away from 3.10 since it is not officialy supported yet. Any other tips?
