[Xen-users] limited number of tap:aio disks - only 64 devices

[Michael Borokhovich <michaelbor@xxxxxxxxx>]

Hi,

I'm running Debian Lenny and xen. Is there any default limitation on creating tap:aio disks?
I have two tap:aio disks per VM and can run only 32 VMs, i.e., only 64 tap:aio devices. Creating the next device gives:

Error: Device 769 (tap) could not be connected. Setting up the backend failed. See the log files in /var/log/xen/ for details.

On other server we run Debian Etch and there are more than 120 VMs are running (240 tap:aio devices).

Thanks in advance,
Michael.
