Max number of loop devices is configurable in the kernel config: you''ll need to recompile dom0''s kernel to support more than 8 devices (the default).

Le mercredi 11 mai 2005 à 13:45 -0700, andrew mathes a écrit :> I can''t seem to increase the # beyond 8 ...if you have compiled loop device directly in kernel, then max number of device should be specified via grub command line _but_ if you have compiled it as modules, then you got to passe max_loop=x as argument to the modprobe command ie: # modprobe loop max_loop=32 you may also need to create more device node, check your /dev/loop* or, maybe the modules is autloaded during boot time, with num of device set to 8 ( default value ). you should configure your autoloader to pass max_loop=x to it hopes this helps cheers -- mlist <mlist@opendoor.fr> opendoor.fr _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
i just wanted to verify ... is this REALLY your kernel boot line, and do you have more than 8 loopback devices running? because it only worked for me having max_loop on the 2nd line, otherwise it wouldn''t let me do it. and if you don''t have more than 8 loopback devices running, the snootiness isn''t appreciated, especially if you''re not 100% sure that you''re right. so my fault if yours is actually working in the configuration you have there, but the attitude is still unnecessary. so for anyone else ... try it on the vmlinuz line as well have a nice day On Wed, 11 May 2005, Kip Macy wrote:> In the future check the FAQ first, here is my grub line: > kernel /xen-3.0-debug-untested.gz dom0_mem=524288 max_loop=255 > com1=9600,8n1 cdb=com1 console=com1 hz=1000 > > On 5/11/05, andrew mathes <amathes@backnine.org> wrote: >> I can''t seem to increase the # beyond 8 ... >> >> i''m just using stock xen0 and xenU, here is my grub line: >> >> title Xen 2.0 / XenLinux 2.6.10 >> kernel /xen.gz dom0_mem=256000 >> module /vmlinuz-2.6.10-xen0 root=/dev/md1 max_loop=32 console=tty0 ro >> >> from all i can figure this should make it 32 ... anyone point me in the >> right direction? >> >> thanks again! >> >> _______________________________________________ >> Xen-users mailing list >> Xen-users@lists.xensource.com >> http://lists.xensource.com/xen-users >> > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You can increase this number by setting max_loop=32 (etc) on the domain 0 kernel command line in Grub." I understand the domain 0 kernel command line in GRUB should be the one after "kernel" and titled "module" that is responsible for starting the dom0 kernel. If I am wrong, may be the FAQ should be rephrased in order to make that more clear to others. Pehraps an example should help. -- Bye, Fernando Maior LPIC/1 31908 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I was responding to Andrew''s comments not yours. And yes it looks like something has changed with the loopback devices in more recent versions of the linux kernel. max_loop=255 worked on 2.6.9 for an earlier version of 2.0-testing. It appears that this option no longer works. You might try taking a look at the loopback driver to see if anything jumps out. I might have to take a look at this at some point if it isn''t fixed in the next month or so. -kip On 5/22/05, Fernando Maior <fernando.souto.maior@gmail.com> wrote:> On 5/21/05, Kip Macy <kip.macy@gmail.com> wrote: > > I fail to understand your attitude - I apologized 2 minutes after your > > initial response.
