  1. Time zone differs in graphs and logs in PVE web gui

    Hello, it's been ages since I saw this first time (I believe it was on 1.8), and yet today, on 3.3, it's still there. When I use PVE web gui I see graphs in server's time zone, while logs below - in my local. If server is near me (that's in my TZ) then these timestamps are the same so no...
  2. PVE uses swap while RAM is*enough, why?

    Recently I got a chance to install PVE 3.3 on quite a capable server (Dual 6-core Xeons, 128 RAM, SSD disks). Due to fact it has a lot of RAM I set up swap to only 8Gb thinking I'll newer need any (and I hate to spend SSDs for swap, too). I created and run some VMs, and as I finished I have 126...
  3. Configure install via boot parameters?

    Try to use http://pve.proxmox.com/wiki/Quick_installation boot params to use disk the way I like, and here is what I miss: there are maxroot, swapsize, maxvz and minfree params. Is the sum of that sizes is the whole size of storage? Or simple maxroot+swapsize+maxvz=total size, and minfree is...
  4. PVE on SSDs?

    Hello, recently I got a chance to try PVE on server with SSD drives. The machine is equipped with Adaptec 5405 card with battery, and 2 x 500 Gb SATA HDDs + 2 x 256 Kingston SSDs. I planned to set up PVE on mirror made of HDDs (so PVE itself and backup will be there; 500 Gb storage is quite a...
  5. Win2003R2 in KVM VM is slow in PVE 2.2 when multiply CPU cores allowed

    Hello! we run Windows 2003 R2 x32 server for quite a long time now (since first 2.x release I believe) in KVM VM and all that time OS was running smooth and fine. Tha machine is like this: boot: c bootdisk: virtio0 cores: 2 cpu: host memory: 4096 name: Server net0...
  6. PVE/KVM and a lot of RAM

    Hello, here is the config problem I face: if I need to run as fast as it possible two windows guest machines (win 2003 r2 x86) with 4 Gb of RAM each, if I have say 16 or 32 Gigs of RAM in the host server will there be any significant difference in VMs speed due to in-RAM caching on host...
  7. KVM: disks on tmpfs?

    Hello, I try to speed up my Win 2003 r2 x86 KVM machine. Due to fact the machine is 32 it can not access more that 4 Gb of RAM (well, even lower value), and the load is pretty high, so it uses swap high enough. As my host server has 32 Gb of RAM, I was wonder if it is possible to create some...
  8. How to list running VMs (and their options) from script?

    Hello, I try to make some monitoring system to check which VM are running/non running on given server. It is easy to check from web interface, but I can't check it from bash scripts. So, may I ask you for advice - how can I check which VMs are running now from script or shell? Another thing...
  9. Several VLANs on single virtual LAN in KVM

    Hello, I wonder if it is possible to create some vmbr, attach it to KVM-based VM, and, inside this VM, to use it as eth0.1, eth0.8, so I can see VLAN ID in its name? See, I use several VLANs in my VM but each of it attached to separate vmbr and from inside VM I see it as separate eth's. Due to...
  10. Offline migration and where settings are stored at?

    Hello, I'm in process of testing 2.0 branch. As far, everything looks nice, but I got a few questions to check before I consider migrating from my current 1.9 servers: 1. Is there are way to read and edit VM settings not from GUI? In 1.9 I can find VM config at /etc/qemu-server/*.conf file...
  11. full-upgrade given strange situation

    I tried to update Proxmox 2.0 to last version with aptitude full-upgrade, and finally got a lot of 'disagrees about version of symbol module_layout' and 'invalid module format' messages on boot, and a lot of modules won't load at startup. Both modules and kernel are 2.6.32-6-pve, and I simply...
  12. VLANs won't work

    My setup is simple, a PC with 1 CPU (decent desktop PC with AMD Phenom II X4 and 2 Realtek NICs). One NIC connects to backup host, and work perfectly, but the othe one point to network and should support VLANs. I set up default VLAN (1) and two other VLANs to test the situation: eth0.7...
  13. Proxmox (KVM) vs Hyper-V as failover cluster hosts

    Don't want to start another holy war, but I really need arguments to implement Proxmox and not Hyper-V on some of my company's servers. My colleagues are to give Hyper-v a chance, I'm not. Our aim is to shorten VMs downtime in case of hardware failure. That is, if in cluster of two...
  14. Real HA - if it is possible with 1.8?

    Hello, hope my questions won't be too silly. I've tried cluster config of two Proxmox PCs with DRBD (though my DRBD performance was too poor, I believe it just question of tuning it up) and I've found ability to live migrate VMs from one host to another is something really nice. But beside...
  15. FS over LVM over DRBD?

    Hello, I use Proxmox in cluster configuration and use DRBD (poor man's shared storage) to use live migration feature (I use KVM). In fact, the VM images are stored on LVM VG, not on "real" file system, so I just can not create disk image of type different from "raw". Lack of filesystem is...
  16. VLANs in cluster - traffic won't run through

    Hello, I see very strange situation, I just can't make VLANs on Proxmox cluster to work. Here is the setup: PC with one on-board NIC and another NIC in PCI slot: eth0: RTL8168d/8111d at 0xffffc90011fd0000, 6c:62:6d:e7:fe:4e, XID 081000c0 IRQ 27 eth1: RTL8169sb/8110sb at 0xffffc9000145ac00...
  17. How to migrate KVM VM from cli?

    Hi, I'm trying to setup (kind of) HA cluster with two Proxmox servers. I've set up cluster and DRBR, and I'm able to do live migrate KVM VMs from one server to another. Now I need to do that automatically as server goes down. As far I think I can user heartbeat program to track the fact that...
  18. Setup with DRBD: won't able to do migration (either live or not)

    Hello, I'm a bit newbie in DRBD-backed cluster config, and face pretty strange behaviour of cluster that is build strictly by manual: I set up two identical machines (these are desktop PCs, I took them for test purpose, but the hardware is good so I believe It should work with no problem): -...
