Various config and setup notes

libvirt/kvm

Connecting to remote from OSX

virsh -c qemu+ssh://usrname@host/system?socket=/var/run/libvirt/libvirt-sock

Connecting to the server will result in an error : "hangup / error event on socket". It turns out that the macosx client assumes the socket resides in /usr/local/lib whereas the ubuntu server has the socket in /var/run/libvirt/libvirt-sock — http://www.planetdevops.net/index.php/category/libvirt/

Creating a new Debian Wheezy with net install

http://www.server-world.info/en/note?os=Debian_7.0&p=kvm&f=2

virt-install
-n www
-r 2048
-f /var/kvm/images/www.img
-s 20
--vcpus=2
--os-type linux
--os-variant=debianwheezy
--network bridge=br0
--nographics
--location='http://ftp.riken.jp/Linux/debian/debian/dists/wheezy/main/installer-amd64/'
--extra-args='console=tty0 console=ttyS0,115200n8 serial'

Newer version, with spice:

virt-install
--name popov
--ram 1024
-f /home/libvirt/images/popov/popov.img -s 5
--vcpus=2
--os-type linux
--os-variant=debianwheezy
--network bridge=br0
--location='http://ftp.riken.jp/Linux/debian/debian/dists/jessie/main/installer-amd64/'
--extra-args='console=tty0 console=ttyS0,115200n8 serial' --graphics spice,listen=0.0.0.0

Creating and marking default network for autostart

This is needed for autostart VMs to actually autostart

# virsh net-start default
# virsh net-autostart default

Marking a domain for autostart

# virsh autostart domainname

Start a domain without defining

# virsh create domaindef.xml

Defining a domain from xml without virt-install

# virsh define domaindef.xml

Mount a qcow2 image

modprobe nbd max_part=63 qemu-nbd -c /dev/nbd0 image.qcow2 mount /dev/nbd0p1 /mnt/p1

Linux in general

No bullshit wlan setup:

Add to /etc/network/interfaces:

auto wlan0
iface wlan0 inet dhcp
  wpa-ssid <ssid>
  wpa-psk  <password>

Monitor filesystem events

apt-get install incron

incrontab -l prints user incrontab

Windows XP Activation Loop

See: http://troubleshooting-101.blogspot.ru/2012/02/windows-xp-activation-loop-cant-log-on.html

In full Safe Mode:

regsvr32 regwizc.dll
regsvr32 licdll.dll
rundll32.exe syssetup,SetupOobeBnk

It is important to wait a few minutes until the last command stops background processing before rebooting into normal mode.
