How to migrate from KVM-libvirt to PROXMOX

I partially answered my own question. Yes for option one but I am using identical servers. What if the servers were not identical? Should the VM work when moved?

Anyway, if it helps anyone, here is what I did to move a Win2000 VM from a kvm-based Ubuntu 9.04-server amd64 to a server running proxmox 1.4 beta2. My transfer medium was an external usb drive formatted using ext3.

#Backup On Prod Server
# Plug in usb drive and locate drive. You might want to use fdisk to help. In fdisk type 'p' to list partitions. 'm' for help.
fdisk /dev/sdb
# mount drive if not mounted
mkdir /mnt/drive2
sudo mount /dev/sdb1 /mnt/drive2

# Find LVM file to copy
sudo lvdisplay
sudo dd if=/dev/vmgroup/vm52 of=/mnt/drive2/vm_2000.dd
ls -lh /mnt/drive2/
sudo umount /mnt/drive2

#Migrate to New Server
# Plug in usb drive and locate drive. See directions above
mkdir /mnt/drive2
sudo mount /dev/sdb1 /mnt/drive2
ls -lh /mnt/drive2/

# Locate desired VM to replace and rename. They are in the images folder.
ls -hl /var/lib/vz/images/103
mv /var/lib/vz/images/103/*.raw /var/lib/vz/images/103/vm-103-disk-1.raw.back

# Copy the external usb file to the proxmox lvm
dd if=/mnt/drive2/vm_2000.dd of=/var/lib/vz/images/103/vm-103-disk-1.raw

# Clean-up
rm /var/lib/vz/images/103/vm-103-disk-1.raw.back

# Unmount
sudo umount /mnt/drive2

Enjoy!

RALINK 5360 ..how to install dwa 525 with chipset ralink 5360 on ubuntu 10.04

Re: RALINK 5360 ..how to install dwa 525 with chipset ralink 5360 on ubuntu 10.04..

I love a challenge and so will you, I hope. This is a relatively new device and we are going to have to experiment a bit. Please download RT539x PCIe here: http://www.ralinktech.com/en/04_supp...ort.php?sn=501

Download it to your desktop. Right-click it and select 'extract here.' It is handily a bz2.bz2 file, so you may have to 'extract here' a couple of times. Good work, Ralink! Now open a terminal and, with an internet connection, do:

Code:

sudo apt-get install linux-headers-generic build-essential

Open the folder you extracted and drill down to os/linux/config.mk and with a text editor change:

Code:

HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

Proofread, save and close the text editor. Now open the file os/linux/pci_main_dev.c with a text editor. Make the addition I've highlighted here:

Code:

#ifdef RT5390
 {PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC5390_PCIe_DEVICE_ID)},
 {PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC539F_PCIe_DEVICE_ID)},
 {PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC5392_PCIe_DEVICE_ID)},
 {PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC5362_PCI_DEVICE_ID)},
        {PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC5360_PCI_DEVICE_ID)},
#endif /* RT5390 */

Everything before and after is unchanged. Spacing, punctuation, brackets, etc. are crucial. Proofread carefully twice before you save and close the text editor. Now back to the terminal:

Code:

cd Desktop/2011

Press Tab and the rest will fill in automagically. Press Enter.

Code:

sudo su
make
make install
modprobe rt5390sta
echo rt5390sta >> /etc/modules
exit

Your wireless should now be working.

Installing PostgreSQL 9.1 on Ubuntu 10.04

27 Replies

PostgreSQL 9.0 final was released on 2010/09/20 which I’ve been waiting for to begin playing with it and evaluating it. The mainline Ubuntu Lucid apt repositories only have 8.4. According to the package maintainer, Martin Pitt, the postgresql-9.0 package won’t be added until Ubuntu Natty. Thankfully, he setup a backports repo for Ubuntu that we can pull from.

This is a very quick and painless process. If you have not done so already, make your life easier by installing python-software-properties:

sudo apt-get install python-software-properties

Next up is adding the backports repo and updating apt:

sudo add-apt-repository ppa:pitti/postgresql
sudo apt-get update

UPDATE: In the comments, Jason Froebe points out that if you already have an earlier version of PostgreSQL installed, you can just upgrade it:

sudo apt-get upgrade

Finally install postgresql-9.1:

sudo apt-get install postgresql-9.1 libpq-dev
The libpq-dev package is for compiling wrappers/clients against libpq.

There you’re done!
