Re: [OpenIndiana-discuss] KVM Failed to allocate memory: Resource temporarily unavailable
If you have the disk space, you might be as well creating a swap size of memory x 2. Old Solaris used to suggest you set it to memory x 4, but that was when memory was limited and expensive.

Re: [OpenIndiana-discuss] KVM Failed to allocate memory: Resource temporarily unavailable
how much swap do you have? KVM automatically allocates the same amount of swap as memory when you start an instance, if you don't have the free swap it won't work.
