I have a DomU that mounts some loop back files (file:/f1,f2,f3,f4...), and after this virtual machine to be up, does not obtain more to mount loop back files in the Dom0. I receive the following error: # mount -o loop /f9 /mnt/f9 mount: could not find any free loop device Where it could increase this capacity? It would be insufficient RAM memory? -- Leonardo Pinto listas#openlogic dot com br ------------------------------------------------------------------ Esta e'' uma mensagem enviada usando o OpenLogic OwbMail Messaging. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi, Maybe, you will set up the loop back device by default. In Linux, loop back module is set up as using eighth devices. Please find under /dev/loop?. Do you see more than ninth loop devices? If you see only eighth loop devices (loop1 to loop8), please set up loop devices as using more than ninth devices. (for example, set ''max_loop=64'' at boot options or add ''options loop max_loop=64'' into /etc/modprobe.conf) Satoshi UCHIDA> -----Original Message----- > From: xen-users-bounces@lists.xensource.com > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of > Leonardo Pinto > Sent: Friday, June 30, 2006 10:49 AM > To: Xen Users > Subject: [Xen-users] Insufficient loop device free > > I have a DomU that mounts some loop back files > (file:/f1,f2,f3,f4...), and after this virtual machine to be > up, does not obtain more to mount loop back files in the > Dom0.

If I recall correctly, the max amount of loopback devices you are allowed to have is 9. There may be a way to increase that number but I can''t recall off the top of my head Hope that helps On Thursday 29 June 2006 21:48, Leonardo Pinto wrote:> I have a DomU that mounts some loop back files (file:/f1,f2,f3,f4...), > and after this virtual machine to be up, does not obtain more to mount > loop back files in the Dom0.

Ok. Thanks, thanks, thanks...
