Remove limit on number of tap devices
libvirt-0.6.3-26.el5 has been built into dist-5E-qu-candidate with the fix Daniel The bug has been fixed in libvirt-0.6.3-26.el5 I booted thirty-two virtual machines, each with 8 virtual nics on a x86_64 system with libvirt-0.6.3-26.el5 version, there were 256 tap devices created in total, no problem found, when I booted another more one, that's ok also for creating the number of tap devices more than 256. I did the same on libvirt-0.6.3-25.el5, when booting the 33th virtual machines, it reports error: error: Failed to start domain guest21 error: internal error Failed to add tap interface 'vnet%d' to bridge 'virbr1' : Device or resource busy virbr1 is a temporary bridge created for the bug verification.
