VPSIO：￥29.5元XEN HVM-256MB/15GB/250GB 达拉斯

VPSIO是一家年轻的国人VPS主机商，提供基于XEN架构的VPS产品。之前，赵容也介绍过他们提供的洛杉矶webnx机房的XEN产品，不过很多朋友留言表示价格较高，这次给大家带来新的消息，VPSIO也在发展中不断完善产品线，最新推出的基础型套餐，品质依旧，价格就更加平易近人了~

目前VPSIO提供的基础型套餐，数据中心在达拉斯，基于XEN HVM架构，最低一款使用优惠码后每月仅29.5元。

CPU：2 cores

内存：256MB

SWAP：自定义

硬盘：15GB

月流量：250GB

1 IP/SolusVM

【优惠码】ZRBLOG_DALLAS (终身五折)

【测试IP】23.29.113.163

这次VPSIO上线的是基于XEN HVM架构，比较之前的XEN PV有更大的自主性，不再是主机商提供的一成不变的模板，另外，虽然VPSIO主打linux系统产品，但在基础型产品中内置了win PE的ISO，让装windows成为可能！本次基础型产品依然选择了小内存母鸡E3-1230 +16G，下面，我们看看VPS的部分信息(本次并非在linux下测试，全新展示O(∩_∩)O~)
