Xen Paravirtualization

IBM X3105
Opteron 1212, Mem 1 GB

1. Cek compabilitas dari server
cat /proc/cpuinfo |grep svm
flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush mmx fxsr sse sse2 ht nx mmxext fxsr_opt lm 3dnowext 3dnow up pni cx16 lahf_lm cmp_legacy svm extapic cr8legacy ts fid vid ttp tm stc

2. Download
http://www.jailtime.org/lib/exe/fetch.php?cache=cache&media=download%3Acentos%3Acentos.5-2.20080708.img.tar.
bz2

3. Ekstrak file di /vm/centos
isinya :
-rw-r--r-- 1 root root 2098200576 Jul 9 10:22 centos.5-2.img
-rw-r--r-- 1 root root 280 Dec 24 00:34 centos.5-2.xen3.cfg

4. Buat swap
dd if=/dev/zero of=swapimage.img bs=1024 count=128
mkswap swapimage.img

Edit file centos.5-2.xen3.cfg
kernel = "/boot/vmlinuz-2.6.18-92.el5xen"
memory = 256
name = "centos.5-2"
vif = [ 'mac=00:16:3e:13:e4:81, bridge=xenbr0', ]

#dhcp = "dhcp"
disk = ['file:/vm/centos/centos.5-2.img,sda1,w','file:/vm/centos/swapimage.img,sda2,w']
root = "/dev/sda1 ro"

5. Jalankan xm create -c centos.5-2.xen3.cfg
Sering error
mount: could not find filesystem '/dev/root'
Lakukan :
mkinitrd /boot/initrd-2.6.18-92.el5xen-centos5.2.img `uname -r` --with xenblk --with xennet --preload xenblk --preload xennet

Edit file cfg
kernel = "/boot/vmlinuz-2.6.18-92.el5xen"
ramdisk = "/boot/initrd-2.6.18-92.el5xen-centos5.2.img"
memory = 256
name = "centos.5-2"
vif = [ 'mac=00:16:3e:13:e4:81, bridge=xenbr0', ]

#dhcp = "dhcp"
disk = ['file:/vm/centos/centos.5-2.img,sda1,w','file:/vm/centos/swapimage.img,sda2,w']
root = "/dev/sda1 ro"

6. Aktifkan swap
#mount /vm/centos/centos.5-2.img /mnt/tmp/ -o loop
vim /mnt/tmp/etc/fstab/
ubah menjadi
[root@pjbekasi ~]# cat /mnt/tmp/etc/fstab
/dev/sda1 / ext3 defaults 1 1
/dev/sda2 none swap sw 0 0
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0

7. Jalankan #xm create -c centos.5-2.xen3.cfg

Perlu diingat bahwa konfigurasi diatas menggunakan kernel yang sama dengan Domain0
dan initrd berada lokasi yang sama di /boot Domain0

Instalasi Virtualbox 2.0.6 di Ubuntu 8.04

Sebelumnya saya menggunakan Virtualbox untuk versi virtualbox-ose, lalu saya ingin mengupgrade virtualbox yang ada.

#apt-get install virtualbox
Tetapi disini hanya tersedia versi virtualbox-ose, dimana belum mendukung fasilitas usb

Kemudian saya download virtualbox 2.0.6
http://download.virtualbox.org/virtualbox/2.0.6/virtualbox-2.0_2.0.6-39765_Ubuntu_hardy_i386.deb

Install virtualbox
#apt-get -i virtualbox-2.0_2.0.6-39765_Ubuntu_hardy_i386.deb

* akan ada error

trying to overwrite `/lib/modules/2.6.24-21-generic/misc/vboxdrv.ko', which is also in package virtualbox-ose-modules-2.6.22-14-generic
dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:

Coba kita perbaiki
