[Xen-users] XEN 3.4.2 /proc/xen/balloon doesn''t exist
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I am new to XEN. Try to move from vmware and Virtualbox (I use both now).
Unfortunately, Debian Squeeze no longer support xen (out of the box no dom0)
So I am trying to make it myself.
I have installed xen 3.4.2 from source, did make world and installed.
Got the kernel source from from the git repository with the xen patches
following the xen wiki.... compiled dom0 kernel just fine.
I can boot xen, with grup (old something went odd with grub2 for me) and
then it boots my dom0 kernel fine.
Here I got stuck trying to create a hvm instance for installation of OS.
root@rasnew:/etc/xen# xm create -c /etc/xen/test1.cfg
Using config file "/etc/xen/test1.cfg".
Error: [Errno 2] No such file or directory:
''/proc/xen/balloon''
Here is the error I can not figure out. I did search for this and the
common theme you have not enough memory. I am not sure how come ... see
xm info.... it says 6427 MB free
I actually do not have that file, maybe the balloon driver is not
working ?? I checke it is enable in the kernel config:

Now, I can not even boot xen-3.4.2.gz which I built again from source.... I tried the debian package (squeeze has 3.4.2 as well) I can not boot even the hypervisor (and can not downgrade grub2 to the old grub)... I can see that booting xen with the new grub gives a lot of people grief. I tried all the suggestions like dummy=dummy, double the file name on booth multiboot and module lines I also compiled the command line into the dom0 kernel (the 2.6.31.6 from the Jeremy tree). I know that command line is OK since I can boot it again on the bare hardware no problem....

I really like to know if anyone can actually boot the hypervisor built from source with kernel on Debian Squeeze with grub2 .... the kernel included in the source 2.6.18 doesn''t support my ethernet card and pretty old even udev is too old for some stuff (OK I can run everything in domU if I ever can create one :-)) I am not new to linux (started 1997) this maybe the first project I will have to give up on ... virtbox and vmware just worked but I would prefer> > For more information about mounting /proc/xen.> > -- Pasi >-----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAktfHScACgkQcYMbOTV6LVqAwgCfX+NfMTnEqaXW+gbfZOisqax3 4msAoNEXCoDiQH+lWSWmyk0AOAVQzRmL =KS0a -----END PGP SIGNATURE----- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

If anyone made squeeze with grub2 boot xen-3.4.2 with the jeremy''s kernel work on x86_32 I would really love to hear about that...
