...the ninth "xm create" - that VM will start... I did some google'ing and from what I cn tell that error arises due to the lack of loop back devices (there being 8 by default)... I've tried both using MAKEDEV (in my /etc/rc.local) to create a number of loop back devices and put max_loops in my grub,.conf file. For example here is what I have in grub.conf now: title CentOS (2.6.18-274.3.1.el5.centos.plusxen) root (hd0,0) kernel /xen.gz-2.6.18-274.3.1.el5.centos.plus module /vmlinuz-2.6.18-274.3.1.el5.centos.plusxen ro root=LABEL=/ max_loop=64...

Hi, I have installed debian 3.1 on an Intel Pentium D processor 920 ( including vanderpool.) The installation worked fine and i''m able to start guest-domains. When I try to start the 5.th Guest-Domain, I Get the following error: Error: Device 769 (vbd) could not be connected. Backend device not found. this problem exists still if i have shutdown or destroyed all guests, after

Hi, I am using xen 3.1.0 on opensuse 10.3, for more details see below. When I try to start the third domU, then this will not work, I get the error: Error: Boot loader didn''t return any data! When I shutdown an other one, I can successfully start the machine that failed, see my log below. The xen configuration files are all similar to this one: name="FTP"

Hi to the ML. I''m new to VLAN configuration, and combining it to XEN is a bit difficult. I want to use VLAN because it''s possible to "arping" from a domU to an other, and VLAN looks like; the only solution to prevent that. May be I''m wrong if someone got a solution, I may be interrested. I''ve also tryed ebtables, but nothing to prevent arp

The max_loop option causes more loop devices to be preallocated, but also disables dynamic allocation. So maybe this problem is better solved by t...

Is there a switch or config setting somewhere that would allow me to start up more than the default 4 xen DomU instances? I am finding that the CentOS 5 (x86_64) installation only allows me to start up 4 virtual machines at a time. (It is definetly not a lack of cpu resources, memory or disk space.) Any help or pointers, would be much appreciated. Regards, -- Urs Rau
