    Hi, We plan to install backup server with Adaptec 2820SA. It's said thats hardware raid controller: http://linuxmafia.com/faq/Hardware/sata.html My question is simple: Does Proxmox 3.1 or better has compiled driver in kernel ? Regards, michu

    SSH keys regenerate - question

    Hi Dietmar, Thank you very much for reply. In /etc/pve/priv I have authkey.key file. What is the purpose of this file ? Does it file has anything common with id_rsa or id_rsa.pub files ? If no then only one important thing should be placing id_rsa.pub in authorized_keys on other hosts...

    SSH keys regenerate - question

    Hi, I need to regenerate SSH keys pair - typically id_rsa and id_rsa.pub files. My configuration is single PVE host (no cluster). Is it safe to generate new files ? Should I put some files / change files in /etc/pve/priv ? What should I consider if I want create cluster in future ? Regards...

    Proxmox 2.x / 3.x cluster question

    Hi, Sorry for late response. Guys I need to have offline migration functionality like in Proxmox 1.x. I know that Proxmox 2.x and 3.x are basing on corosync while 1.x was basing on ssh and own algorithms. I have a storage for backup (SSHFS) and I know that I can backup/restore machine. This is...

    Proxmox 2.x / 3.x cluster question

    Hi, I need to configure simple 1.x style cluster beetween 2 servers on Proxmox 3.1. I don't need HA, I don't have shared volume. I have only 2 servers with local storage area (HDDs in RAID). I only need to have central aministration and offline migration possibility. Is it possible with Proxmox...

    Proxmox 2.2 hangs at boot

    Like hotwired007 said, it's true. For example my 5.5 TB volume can hang for 3-5 minutes during scan. fsck is terribly slow for ext3 filesystem. Regards, michu

    Virtio network performance and CPU load on different kernels

    I speak about kvm process on host machine. I use newest Proxmox 2.2 with 2.6.32-17. I see that you use rather old AMD Sempron 140. I remember when I was working on old Intel Server with 2.00 Ghz, 2 core cpu. I used to have cpu usage in about 50%-70% for 5 VMs. So maybe this is issue with VT...

    Virtio network performance and CPU load on different kernels

    Sorry, I didn't notice that you use AMD Sempron 140 with 1 core. Looks for rather old cpu. I rememeber when in past I worked with Proxmox 1.x on old Intel Server with 2.0Ghz CPU with 2 cores. I used to have 50-80% of cpu used with 5 VMs.... So maybe there are some issues with VT support in older...

    Virtio network performance and CPU load on different kernels

    Process takes 12% of cpu, but host machine has 8 cores (16 logical cpu's with HT). Machines with 3.2.0 kernel takes about 3-5%. Regards, michu

    Virtio network performance and CPU load on different kernels

    Hi, I'm very confused about that bug. I did a little test today: 1) VM with Ubuntu 10.04.4 LTS (2.6.32-45), 2 cores. 2) VM with Ubuntu 12.04.2 LTS (3.2.0-37), 2 cores. 3) Physical machine with 10.04.4 LTS (2.6.32-45) - standard PC with Realtek 1Gb/s NIC. Proxmox has tg3 driver NIC. All...

    Updates for Proxmox VE 2.2 - including QEMU 1.3

    Re: AW: Updates for Proxmox VE 2.2 - including QEMU 1.3 Thank you for answer. So the only way for me is to try using backported kernel in lucid - can't upgrade distro because I still rely on squid 2.x. Do you know if backported oneiric kernel (linux 3.0) has this bug fixed ??? Regards, michu
