memory

Hi, My PVE box only has 8GB RAM, & I run 2 KVMs- one with 4GB, & the other with 3GB. I'm wondering if I can allocate 4GB to the one which currently only has 3GB, and still have enough for the underlying host processes to run unencumbered. I don't use ballooning, as it's been problematic in...

One of my cluster's node has been reported by zabbix as having Lack of free swap space: Free swap space in % (pve1:system.swap.size[,pfree]): 9.98 % What could cause this and how to resolve? It seems that others nodes don't have such problem.
