I got so inspired by kasperd's idea yesterday that I made this: https://github.com/bjornnorman/decryptfs-ssh I've tried it out a little already and it seems to work brilliantly. It makes it really simple to add/remove keys for passwordless decryption of ecryptfs home folders when using SSH... Like kasperd's original, it hasn't been exposed to a peer ...

As you are using Openstack, when you create a flavour you can specify the rxtx_factor. My understanding is that this is used to calculate a percentage of the rtx_cap on the network that is available to the VM. I'm not sure if all hypervisors will support it however, though so you may need to do some additional digging to see if KVM does.

If you don't want to do any configuration inside the guest, then the only option is a DHCP server that hands out static IP addresses. If you use bridge mode, that will probably be some external DHCP server. Consult its manual to find out how to serve static leases. But at least in forward modes nat or route, you could use libvirt's built-in 'dnsmasq' (More ...

I remember noticing this on here before and the answer appears to be that: when you restart the networking, the vnetX tap devices are not reconnected, causing the VMs to lose connectivity with the bridge With one solution and some workarounds proposed. KVM guests lose connectivity after networking restart

Your KVM instances should be able to saturate your hosts network connection with no issues. My first recommendation here is to upgrade both the host and guest's kernel. The stock CentOS 6.5 kernel does not have great performance for KVM. I'd suggest kernel-lt from ELRepo (or kernel-ml if you're feeling brave). This should give you a decent boost in ...

You don't need to be messing with <memtune><hard_limit>. This is actually a rather dangerous setting when applied to KVM guests. I would remove that section immediately. However, users of QEMU and KVM are strongly advised not to set this limit as domain may get killed by the kernel if the guess is too low. To determine the memory needed for a ...

As far as I know this is not yet supported. When necessary, I work around it by connecting to the Windows VM via RDP (in my case using Remmina, but you can use whatever you like).

VNC has no facility for clipboard passthrough. You might want to try spice, with the proper agents it works quite well.
