Well, when sda2, on which is the /boot/ partition is now sdc2, that looks kind of aproblem to me when the os quits its ramdisk.

And with 3 NICs, two of which are 1Gb/s able and one only 100Mb/s, when eth0 becomes eth2, all the virtual machine lack a bit of bandwidth. If you see what I mean.

thats why we use UUID pointing to the boot partition instead of /sdx ...

Code: 
cat /etc/fstab

# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext3 errors=remount-ro 0 1
/dev/pve/data /var/lib/vz ext3 defaults 0 1
UUID=c256ea93-bc9a-42de-83cc-56f10c1f2d6d /boot ext3 defaults 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0
 
... just in the case you did not know it - we do not recommend or support the use of soft raid.
 
Hi,

after updating to the latest version (incl. a reboot of the host), my KVM running Ubuntu does not boot anymore - directly after trying to boot from the harddisk, the following occurs on VNC screen.

unaligned pointer 0x1020101 (number is changing)
Aborted. Press any key to exit.

Pressing a key ends up that the first line is deleted and the 2nd either appears again or it does not react anymore.

pve-manager: 1.8-15 (pve-manager/1.8/5754)
running kernel: 2.6.32-4-pve
proxmox-ve-2.6.32: 1.8-32
pve-kernel-2.6.32-4-pve: 2.6.32-32
qemu-server: 1.1-30
pve-firmware: 1.0-11
libpve-storage-perl: 1.0-16
vncterm: 0.9-2
vzctl: 3.0.24-1pve4
vzdump: 1.2-11
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.14.0-2
ksm-control-daemon: 1.0-5

Any ideas?

Yes, indeed. .. Obviously. Shame on me not having been used to that.:(

Do you have a similar solution for the NICs ?
 
try downgrading the pve-qemu-kvm package and try again.

download the 1.7 package:

Code: 
wget ftp://download.proxmox.com/debian/dists/lenny/pve1.7/binary-amd64/pve-qemu-kvm_0.13.0-3_amd64.deb
and install:
Code: 
dpkg -i pve-qemu-kvm_0.13.0-3_amd64.deb
no reboot of the host needed, just stop/start of all KVM guests.

do you run the latest kernel inside your KVM guest?

please use UUID in fstab

'udev' prevents that, so this can't happen (devices are renamed by udev).
 
Thanks Tom, that did it for me until i'd update again ;-)

The kernel inside Ubuntu 10.10 should be up to date - at least I dont get any update offers (2.6.35-28-generic)

Anything you want me to test?
 
post your VMID.conf file from the KVM guest, lets see if I can reproduce it.
 
name: desktop
ide2: none,media=cdrom
bootdisk: ide0
ostype: l26
ide0: local:202/vm-202-disk-1.raw
memory: 1024
sockets: 1
vlanu: rtl8139=CE:BD:BC:25:13:40
onboot: 0
cores: 1
args: -vga vmware
 
I am pretty sure its vmware vga related, remove this line and test again. can you confirm this?
 
Yes, confirmed - its working now with the latest updates installed.

But please note that this line was not added by hand - seems that Proxmox GUI added it at time of KVM creation.

thanks for testing.

no, thats just not possible. the gui never adds 'args:'
 
No problem - its just a test KVM so it has fulfilled its purpose :-)

Ok, maybe I added it to fix another issue but I dont remember anymore (maybe I should add a SVN to keep track of my changes ;) )

I may be wildly off track, but recently ran into what seems to be the same problem on my Proxmox VE 1.7 system that you are describing here, albeit in a completely different context. Essentially my four ethernet NIC's were renumbered from eth0, eth1, eth2, eth3 to eth4, eth5, eth6, eth7, thereby causing numerous problems.

The solution was to delete:

/etc/udev/rules.d/70-persistent-net.rules

For your sanity, you may want to back up this file first, though I don't believe deleting it will cause any damage. YMMV, good luck!

Does Proxmox VE 1.8 support Kernel Samepage Merging (KSM) out of the box? I just installed it, but when I look, I don't see it enabled:

proxmox:/sys/kernel/mm# grep KSM /boot/config-2.6.32-4-pve
# CONFIG_KSM is not set
proxmox:/sys/kernel/mm# cd /sys/kernel/mm/
proxmox:/sys/kernel/mm# ls
hugepages
(no ksm subdir)

so do I need to follow the instructions at http://pve.proxmox.com/wiki/Proxmox_VE_Kernel and run:

aptitude update
aptitude safe-upgrade
aptitude install proxmox-ve-2.6.35

to install the 2.6.35 kernel with KSM support?
 
I couldn't get kernel 2.6.35 to install, but I reran
aptitude update
aptitude safe-upgrade
aptitude install proxmox-ve-2.6.35

again and then it installed 2.6.35 fine. thanks

Hi to all

Proxmox VEe is a great product and never gave me problems from more than a year.

Unfortunately in the last case I had the same problemf of gbrucker with a guest ubuntu server (Zential) and I solved the problem reading your help the to him.

After this, I updated the guest to the last kernerl

Linux server 2.6.32-30-generic-pae #59-Ubuntu SMP Tue Mar 1 23:01:33 UTC 2011 i686 GNU/Linux

and after I upgraded again proxmox.

The guest don't want to start and give back with the same error. The only way was to roll back to the previous configuration pve-qemu-kvm_0.13.0-3.


This is my VMID,conf

name: atlante
ide2: none,media=cdrom
bootdisk: ide0
ostype: l26
ide0: local:105/vm-105-disk-1.raw
memory: 2048
onboot: 1
sockets: 2
boot: cad
freeze: 0
cpuunits: 1000
vga: std
acpi: 1
kvm: 1
cores: 2
vlan0: rtl8139=9E:3C:CC:EE:AA:8B
vlan1: rtl8139=EE:19:D4:D5:FC:4F
