Linux虚拟机试过很高规格都能够正常运行,但今天Windows2012虚拟机创建居然都奇怪而且毫不讲理地蓝屏了
节点资源开超线程48核心,OpenStack预留4个,剩下44个,超售比2,一共可以虚拟化使用88VCPU
在使用如下flavor创建windows虚拟机
+----------------------------+-------------------------+ | Property | Value | +----------------------------+-------------------------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | disk | 40 | | extra_specs | {"ecus_per_vcpu:": "4"} | | id | 134 | | name | flavor_134 | | os-flavor-access:is_public | True | | ram | 65536 | | rxtx_factor | 1.0 | | swap | | | vcpus | 32 | +----------------------------+-------------------------+
出现了蓝屏,出错重启

可是当VCPU个数为24的时候,系统正常
+----------------------------+-------------------------+ | Property | Value | +----------------------------+-------------------------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | disk | 40 | | extra_specs | {"ecus_per_vcpu:": "4"} | | id | 133 | | name | flavor_133 | | os-flavor-access:is_public | True | | ram | 65536 | | rxtx_factor | 1.0 | | swap | | | vcpus | 24 | +----------------------------+-------------------------+
导致的问题就是Resize时候容易出错风险,影响使用
暂时原因未知,难不成还和跨CPU有关
日后持续分解
