====== Multiple Socket Issues ======
----
**Problem:**  Only two sockets show up in Windows.

**Fix:**  go to manual topology in the CPU section of Virt-Manager and have at most 2 sockets and use multiple cores to get more CPUs in Windows.

**Why:** Windows only supports two CPU sockets, so any more than two sockets are ignored by Windows

====== No Sound in Spice in 13.10 ======
----
**Problem:** No sound from guest

**Fix:** Go to application volume and set it to the max level

**Why:** For some reason pluseaudio sets audio levels for spice client to very low level.
