Re: [one-users] Hung sshd processes on VM hosts
I've never had this problem myself but a thing worth trying is reusing the connection. In ~oneadmin/.ssh/config we can add these lines: --8<-- Host * ControlMaster auto ControlPath ~/.ssh/sockets/%r@%h-%p ControlPersist 600 -->8-- And create the directory ~oneadmin/.ssh/sockets. The first time it connects to a host a new file will be created and will be reused for the next connections to the same host. I hope it fixes or alleviates the problem.

[one-users] Architecture advice
Hi to all i'm planning a brand new cloud infrastructure with opennebula. I'll have many KVM nodes and 3 "management nodes" where I would like to place OpenNebula, Sunstone and something else used to orchestrate the whole infrastructure Simple question: can I use these 3 nodes to power on OpenNebula (in HA-Configuration) and also host some virtual machines managed by OpenNebula ? For example: node1 (the same for all 3): - Debian Wheezy with KVM - One manually-created KVM virtual machine with OpenNebula on it (and keepalived/ucarp for redundancy) - Many KVM virtual machines managed by OpenNebula First KVM virtual machine will obviously manually managed, because OpenNebula can't manage it self. In this case I'll have a full virtualized infrastructure, with just 3 virtual machine out of opennebula (the opennebula machines itself) Evertything else will be managed by opennebula. Any suggestions ? Probably i'll use 2 distinct LVM volume groups to split OpenNebula VM and VM storage used by VM managed by opennebula. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
