VirtualBox: USB2.0

If you want to enable usb 2.0 in your vbox, you should install Oracle extension pack:

# wget http://download.virtualbox.org/virtualbox/4.1.6/Oracle_VM_VirtualBox_Extension_Pack-4.1.6-74713.vbox-extpack

1
# VBoxManage extpack install

Oracle_VM_VirtualBox_Extension_Pack-4.1.6-74713.vbox-extpack

after you should enable usb in virtual machine settings.

PS: Apple devices needs in usb 2.0 !

openvz: how to change vid

Here is an example how to change CTID from 106 to 105:

    host# vzctl chkpnt 106 --dumpfile /tmp/106.dump
    host# mv /etc/vz/conf/106.conf /etc/vz/conf/105.conf
    host# mv /vz/private/106 /vz/private/105
    host# mv /vz/root/106 /vz/root/105
    host# vzctl restore 105 --dumpfile /tmp/Dump.106

KVM virtualization

I will use kvm with libvirt and qemu:

- install next packages: kvm libvirt-bin python-virtinst bridge-utils
- adduser $YOURUSERNAME libvirtd
- reboot
- user@kvmhost:~$ virsh -c qemu:///system list --all
Id Name State
---------------------------------- 

if we have linux ubuntu, then bridge network will install very simply:
- edit /etc/network/interfaces

before modification:

auto eth0
iface eth0 inet static
       address 172.16.4.24
       netmask 255.255.255.192
       network 172.16.4.0
       broadcast 172.16.4.63
       gateway 172.16.4.1

after modification:

auto eth0
iface eth0 inet manual
auto br0
iface br0 inet static
        address 172.16.4.24
        netmask 255.255.255.192
        network 172.16.4.0
        broadcast 172.16.4.63
        gateway 172.16.4.1
        bridge_ports eth0
        bridge_fd 9
        bridge_hello 2
        bridge_maxage 12
        bridge_stp off
