vcpu 的速度在 T4-2 的 guest domain 中显示为 “-1446 MHz” (Doc ID 1641454.1)

Last updated on MAY 17, 2019

适用于:

SPARC T4-2 - 版本 All Versions 到 All Versions [发行版 All Releases]
Oracle Solaris on SPARC (64-bit)

症状

在 control domain 使用 Solaris 10 U11、guest domain 使用 Solaris 10 U7 的环境中,在 guest domain 中执行 prtdiag -v 查看硬件信息时发现 CPU 的频率是 -1446 MHz,control domain 中则显示正常。

1. Guest domain 中的 prtdiag 显示所有 vcpu 的频率都是 “-1446 MHz”。

$ cat sysconfig/prtdiag-v.out
System Configuration: Sun Microsystems sun4v SPARC T4-2
Memory size: 245760 Megabytes

================================ Virtual CPUs ================================


CPU ID Frequency Implementation Status
------ --------- ---------------------- -------
0 -1446 MHz SPARC-T4 on-line
1 -1446 MHz SPARC-T4 on-line
2 -1446 MHz SPARC-T4 on-line
3 -1446 MHz SPARC-T4 on-line
4 -1446 MHz SPARC-T4 on-line
5 -1446 MHz SPARC-T4 on-line
6 -1446 MHz SPARC-T4 on-line
7 -1446 MHz SPARC-T4 on-line

2. psrinfo -v 显示的 CPU 频率是正确的。

Status of virtual processor 0 as of: 03/24/2014 09:52:27
  on-line since 12/22/2013 19:47:30.
  The sparcv9 processor operates at 2848 MHz,
        and has a sparcv9 floating point processor.

        and has a sparcv9 floating point processor.

更改

1. 这台 T4-2 的 control domain 安装的是 LDM v3.0.0.3,control domain 的 OS 使用的是 Solaris10 U11。

# ldm -V

Logical Domains Manager (v 3.0.0.3)
       Hypervisor control protocol v 1.11
       Using Hypervisor MD v 1.4

System PROM:
       Hostconfig      v. 1.3.3.g      @(#)Hostconfig 1.3.3.g 2013/10/28 10:36
       Hypervisor      v. 1.12.3.c     @(#)Hypervisor 1.12.3.c 2013/09/10 14:50
       OpenBoot        v. 4.35.3       @(#)OpenBoot 4.35.3 2013/08/05 11:35

 

2. 但 guest domain 安装的 OS 版本是 Solaris10 U7 (5/09),kenerl 版本是 139555-08。
