Hi,

I downloaded Xen 4.0 and did:
make install
I donot see initrd (ramdisk) being created at all.

Any suggestions ?

Thanks,
CM

Step 5 of the README
   Depending on your config, you may need to use 'mkinitrd' to create
   an initial ram disk, just like a native system e.g.
    # depmod 2.6.18-xen
    # mkinitrd -v -f --with=aacraid --with=sd_mod --with=scsi_mod
initrd-2.6.18-xen.img 2.6.18-xen
   Other systems may requires the use of 'mkinitramfs' to create the
   ram disk.
    # depmod 2.6.18-xen
    # mkinitramfs -o initrd-2.6.18-xen.img 2.6.18-xen

You may need to change the kernel version based on what you built.
Also some distros use different commands to build initrd files.

I actually forgot about this step for a second too.

Thanks,
Todd

The #5 of README is not clear in details.
which directory to run depmod and mkinitrd from ?

I see:

# depmod xen-4.0.0 
WARNING: Couldn't find symtab and strtab in module xen-4.0.0

# ls -l
total 1356
-rw-r--r-- 1 root root 1380620 May 13 13:05 xen-4.0.0


Any suggestions ?

depmod is referring to the kernel version.
You can run it from anywhere, it will look in /lib/modules for the
kernel modules directory.

Example:

# ls /lib/modules
2.6.31.13                              2.6.33.1-24.fc13.x86_64

# depmod -a 2.6.31.13
(no output, sometimes ignorable warnings)

the mkinitrd will also refer to that same kernel version

For example:
mkinitrd /boot/initrd.img-2.6.31.13 2.6.31.13

Hope that helps.

Todd

It doesn't matter.

Wrong. You need to run depmod for the *kernel*, not for xen.

So like this:
depmod -a 2.6.32.12

Or whatever is your kernel version.
