Description of problem: I have 1025 shutdown guest and when I want to list them all there is an error # virsh list --all error: Failed to list inactive domains error: too many remote undefineds: 1025 > 1024 error: Reconnected to the hypervisor For running guests, virsh list --all can work well # virsh list --all |wc -l 1028 Version-Release number of selected component (if applicable): libvirt-0.9.10-6.el6.x86_64 qemu-kvm-0.12.1.2-2.262.el6.x86_64 kernel-2.6.32-250.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1. Define 1025 guests 2. run # virsh list --all 3. Actual results: Report error Failed to list inactive domains error: too many remote undefineds: 1025 > 1024 error: Reconnected to the hypervisor Expected results: Should not have this limitation because 1024+ guests have already supported Additional info:
Osier, I believe this has been fixed; can you comment with the commit id and close CURRENTRELEASE?

This is needed to cover some corner cases where libvirt is run on such huge machines that their capabilities XML is 4 times bigger than our current limit. This leaves users with inability to even connect. commit a2c304f6872f15c13c1cd642b74008009f7e115b Author: Michal Privoznik <mprivozn@redhat.com> Date: Thu Apr 26 17:21:24 2012 +0200 rpc: Switch to dynamically allocated message buffer Currently, we are allocating buffer for RPC messages statically. This is not such pain when RPC limits are small. However, if we want ever to increase those limits, we need to allocate buffer dynamically, based on RPC message len (= the first 4 bytes). Therefore we will decrease our mem usage in most cases and still be flexible enough in corner cases.
