Hello,
Thanks.
1) I am working on 32 bit x86.
2) I triled with the default, unchnaged xend-config.sxp (taken from
/dist/install/etc/xebn)
I ran:
tail -f /var/log/xend.log
xm migrate myDomU 127.0.0.1
I want to add something:
I think my memory division for domo and domU is OK,
but I am not sure:
This was done on a machine with RAM 128 MB.
in grub.conf I have this allocation:
kernel /boot/xen.gz dom0_mem=60000
and in myDomU config file I have mempry set to 32 MB thus:
kernel ="/boot/vmlinuz-2.6.12.6-xen0"
memory = 32
name = "myDomU"
nics = 1
disk = ['file:/work/dev/tests/feodra_xe_img/fedora.img,sda1,w']
root = "/dev/sda1"
This is the log I got: (seems to be a problem with restore:
I see "Failed to increase reservation" and other error messages)
