Sorry, I cannot do it right now. I need move boxes back, i.e. very close to each other ( 2.5 m). NULL modem cable is very short. I will do it as soon as i can ( 1-2 days).

Boris: can you make two logs; one with dom0_mem=4096M and another with 4097M. Don''t change anything else between the log captures, only that dom0_mem parameter. -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Problem with serial console output. Grub Entry on testing box:- title Xen 3.5 Serial / Ubuntu 9.04 Jaunty (kernel 2.6.31-rc8) kernel /xen-3.5.gz dom0_mem=1024M loglvl=all guest_loglvl=all com1=19200,8n1 console=com1 module /vmlinuz-2.6.31-rc8 ro root=/dev/sdc2 console=hvc0 earlyprintk=xen module /initrd-2.6.31-rc8.img On connected box in text mode:- # cat /dev/ttyS0 | tee log I am getting unreadable output Source box - Ubuntu 9.04 Server installed in location RU,Moscow Target box - Fedora 11 installed in location RU,Moscow I suspect it to be a reason of the issue.

Change the xen-3.5-gz line in grub.conf to have "com1=9600,8n1", maybe that''s a better default.. Or then don''t use "cat /dev/ttyS0", but use "minicom" instead.. and configure the speed etc there (I think it''s O or P to go to configuration).
