Problem upgrading from VE 2.1 to VE 2.3

Hi guys new to the forum-

Recently I upgraded my proxmox host from VE 2.1 to the most recent release VE 2.3-13/7946f1f1. After doing so I noticed that the I/O performance on all of my VM's went south (Currently using NFS share on my freenas box for all VM storage needs (never had performance issues before).At first I thought maybe it was my gigabit switch that was to blame or maybe a bad nic however that was not the case and I have since ruled that out. Can anyone shed some light on this issues? Maybe i missed a step during the move to the latest build.

Any help is greatly appreciated :cool:

Proxmox 2.3 - df in ovz containers wrong

April 30, 2013, 12:18 am

g'day,

just installed a Proxmox 2.3 node, and moved an ovz container from a CentOS based node to the new Proxmox node. I know that there are about 20G taken in the VM out of 30G allocated, yet df inside the container only displays 600M in use - how come? The VM is a cPanel CentOS VM, if that helps. A second VM (also with cPanel) has the same issue. Reporting 2G taken out of 200G, when I know over 100G are taken already (node df is fine).

any ideas?

cheers,

VM drive cache mode and performance

Hello everybody,

Could anybody try to explain why cache=directsync and cache=none (which is write-back with host cache disabled) give completely same results? Shouldn't it be better on writing with cache=none?

------------------
Hardware:
- Dell PE 710
- PERC H700 Integrated
- RAID 0+1
- Current Cache Policy: WriteBack, ReadAdaptive, Direct, No Write Cache if Bad BBU
- BBU is in place

Proxmox:
- Proxmox VE 2.3 (is under some daily load during the tests)

Virtual machine:
- Windows 2008 R2 SP1
- 3 drives (virto HDD, 10GB raw image on ext3, i.e. on local storage)
-- drive E: cache=directsync
-- drive I: cache=none
-- drive F: cache=writethrough
------------------

My two cents on Proxmox

Hi everybody,

I'd like to say that you have a great product, with many great features that makes it a good choise to create a corporate virtualization environmet. But I need to say that the poor and few documentation (outdated wiki posts, no man pages, --help almost inexistent) make it almost imposible to choose it for a production environment. If you can take sometime to make documentation more robust and uptodate with the releases, you'll make this plataform a real choise.
I'm affraid that I have to leave to ovirt for this matter as I've installed my nodes with proxmox and planned to buy the license for support, but as everystep is a fight to get info about how to go on.
Keep on this great project and don't miss sight of documentation that is almost as importat as the software itself.

Ceph Performance inside Client

Hi,
I have an 3-node ceph cluster with ssd-journal and 10GE-connection.
Inside an VM (wheezy) I got > 100MB/s troughput with dd - but if I cp (or dd) an big file on the same rbd-disk, the performance drop down to 12MB/s.
The networkperformance between host and ceph-nodes is 9.7 GB/s (iperf).

I have tried different cache options, different OS, different filesystems inside VM...

Any hint?

Win 7 doesnt boot on VE 2.3

We are observing a strange behaviour on a HP Server which is newly installed w Proxmox 2.3-13:
After installing (installation works fine) windows 7 machines they do not boot. After bios messages they stop at 'booting from harddisk'.
We tried different iso files ( which all worked good on a Proxmox 2.2 machine).

What makes it more weird: The vm cant even boot from cd (iso files) until the virtual hard disk with the stalling system is removed.

We tried virtio and IDE. Same result.

Any idea anyone?

add hostname to backup file name

Hi All,

I am trying to add the CTID hostname (openvz containers) to the backup files that are created on these containers. I tried using a hookfile which had no effect while passing the --script hookfile.pl . Can anyone assist ? This is an annoying problem as a container that has CTID 110 can be retaken by a new container if that previous container is destroyed.


#!/usr/bin/perl -w


# example hook script for vzdump (--script option)


use strict;
use File::Copy qw(move);


my $basedir="/mnt/backups/";
print "HOOK: " . join (' ', @ARGV) . "\n";


my $phase = shift;
if ($phase eq 'backup-end' ){
my $mode = shift; # stop/suspend/snapshot
my $vmid = shift;
my $vmtype = $ENV{VMTYPE} if defined ($ENV{VMTYPE}); # openvz/qemu
my $dumpdir = $ENV{DUMPDIR} if defined ($ENV{DUMPDIR});
my $hostname = $ENV{HOSTNAME} if defined ($ENV{HOSTNAME});
# tarfile is only available in phase 'backup-end'
my $tarfile = $ENV{TARFILE} if defined ($ENV{TARFILE});
# logfile is only available in phase 'log-end'
my $logfile = $ENV{LOGFILE} if defined ($ENV{LOGFILE});
print "HOOK-ENV: vmtype=$vmtype;dumpdir=$dumpdir;hostname=$hostname ;tarfile=$tarfile;logfile=$logfile\n";
if ($phase eq 'backup-end' and defined ($tarfile) and defined ($hostname)) {
if ( $tarfile=~/($basedir\/vzdump-(qemu|openvz)-\d+-)(\d\d\d\d_.+)/ ){
my $tarfile2=$1.$hostname."-".$3;
print "HOOK: Renaming file $tarfile to $tarfile2\n";
move $tarfile, $tarfile2;

More than one vm on same core

Hi I have tried to find info on this but can't seem to. I would like to know if it's possible to share the same core across vms. That is to say I have a dual core but I would like 3 or 4 windows vms. The idea is that I don't really need the processing power all of the time. IF you can do that then could I share both cores with all of the vms? Then I would get maximum power at all times? Is this possible or will it cause problems?

high load after processor failed

Hello,

I've a strange problem after the upgrade from 2.1 to 2.3.

In my setup there are two Servers in a cluster. On of them
works without problems, but several times a day the other
server has a realy high load (3-5) and all clients on this host
are freezing.

The only solution to get the server working again is to do a restart.

This Server has a Raid5 on SAS-HDDs, after I added "elevator=deadline" to
grub the problem does not shown itself so often.

In syslog I found this logs, and I think after that the Server got these problems.

I noticed a couple of times now that restoring a vm in 2.3 takes a very long time, much longer than previous version.

Restore time for a Win2003 with 2 HD's (32Gb & 50Gb) took 12 hours. Has anyone else experienced this?

I AM glad for the new backup/restore systems because now the restores work without crashing my entire Proxmox server. But it seems to me this is an excessive time...

PM VE 2.3 browser caching issues

Just curious if anyone else has been having web gui login problems on 2.3 due to browser caching issues. On both Chrome & Firefox (latest as of post date) when I try to load the Proxmox Web GUI I get a blank white screen, no login prompt. Clearing cache works sporadically. Entering "incognito" mode on Chrome works always. Disabling cache in developer mode on Chrome, or in about:config on Firefox also works flawlessly.

In Firefox about:config I first set browser.cache.check_doc_frequency to 1, which is supposed to force a check every load and still did not work. Only completely disabling cache did the trick.

vzmigrate +" DISK_QUOTA=off" FAILS

Hi everyone!

I've two identical servers with Proxmox 2.2 and a GFS2 shared storage. If I migrate an OpenVZ container with "DISK_QUOTA=on" (in vz.conf config file) it almost takes 1 hour on "initializing remote quota" proccess (150GB of small size files).

Otherwise, if I disable quotas globally (DISK_QUOTA=off in vz.conf) and I try to migrate, vzmigrate will try to dump the container quota file which don't exists (quotas disabled). It seems a bug fixed on vzctl >= 3.0.24 (https://bugzilla.openvz.org/show_bug.cgi?id=1094), but for some reason it still fails.

Here I post some logs and info:

Public IP - VM

Hello all,

I want to know the differents solutions for configure any VM with public IP.

I know this solution :
Code:
auto eth0
iface eth0 inet static
        address <pub>
        netmask 255.255.255.0
        network <pub>
        broadcast <pub>
        gateway <pub>

auto vmbr0
iface vmbr0 inet manual
        address <pub>
        netmask 255.255.255.0
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
And I configure an other public IP in the VM.

But I "lost" one public IP.

I would configure directly an public IP for a VM without lost one public IP in vmbr bridge.

Nota: The NAT solution is not possible in my infrastructure principes.

It's possible ?

Thanks

Sharing folders between (virtual) systems

On the Proxmox I have installed three virtual systems:
* Linux Ubuntu server (Ubuntu Linux server has a public IP address)
* 2 x Win7


I need to make on Proxmox system a (read/write) directory accessable by Linux serwer and 2 Win7. At the same time I do not want the directory to be accessible to the public.

Can you suggest me something? Which way to best go (samba?) And how to configure the network?


Regards,
Bartek
