虚机在Cluster内迁，统统失败

在host上ping vmotion 地址可以ping通

检查MTU

get-cluster *** | get-vmhost | Get-VMHostNetworkAdapter -VMKernel | select VMhost, Name, IP, SubnetMask, PortGroupName, vMotionEnabled, mtu | where {$_.VMotionEnabled} | FT -AutoSize

SubnetMask PortGroupName VMotionEnabled Mtu

255.255.255.0 VMotion True 1500
255.255.255.0 VMotion True 1500
255.255.255.0 VMotion True 1500
255.255.255.0 VMotion True 1500
255.255.255.0 VMotion True 1500
255.255.255.0 VMotion True 1500
255.255.255.0 VMotion True 1500
255.255.255.0 VMotion True 1500
255.255.255.0 Vmotion True 1500
255.255.255.0 Vmotion True 1500
255.255.255.0 Vmotion True 1500
255.255.255.0 Vmotion True 1500
255.255.255.0 Vmotion True 1500
255.255.255.0 Vmotion True 1500

统统是1500
但是有个host management portgroup 勾选了 vmotion

uncheck vmotion 选项后，问题解除
