Hi Friends !!!

I have one xen server (debian etch) already in production; there are samba, squid, 2 ldap servers , apache2, postgresql and others, 8 virtual machines at total in a hardware raid5. Now I need a backup system, and i will use bacula with a dell ultrium3 LTO. I would like to know if there are problems with i/o? How can I connect a DomU directly to /dev/st0 of Dom0 ?? Its a very good machine ( 4xXeon 4GB Ram ) , but i'm afraid to run bacula-fd in all DomUs and bacula-dir and bacula-sd in a DomU too, and get I/O problems, or may crash xen , corrupt data... whatever....

Use pciback.hide in grub.conf for you SCSI card attached to your tape drive.

itle CentOS (2.6.18-8.1.4.el5xen)
        root (hd0,0)
        kernel /xen.gz-2.6.18-8.1.4.el5
        module /vmlinuz-2.6.18-8.1.4.el5xen ro root=LABEL=/ 
        module /initrd-2.6.18-8.1.4.el5xen.img

And then allow access to the PCI card in your domU configuration.

kernel = "domU-current"
memory = 256
name = "backup01"
vif = ['ip=]
pci = [ '0000:02:0b.0' ]
dhcp = "dhcp"
disk = ['phy:/dev/vg/disk01,sda1,w', 'phy:/dev/vg/disk01.swap,sda2,w']
root = "/dev/sda1 ro"
