Subject: hw/arm/virt: Fix Manufacturer and Product Name in emulated SMBIOS
|
|
mode
|
|
|
|
Status: RHEL-only
|
|
|
|
In vm, when run 'dmidecode -t system', it outputs different Manufacturer
|
|
and Product Name on x86_64 and aarch64 system. For example:
|
|
|
|
For aarch64 vm:
|
|
Manufacturer: QEMU
|
|
Product Name: KVM Virtual Machine
|
|
|
|
For x86_64 vm:
|
|
Manufacturer: Red Hat
|
|
Product Name: KVM
|
|
|
|
Fixing this issue by changing Manufacturer to 'Red Hat' and Product
|
|
Name to 'KVM' on aarch64 platform. Thus the output is aligned on both
|
|
x86_64 and aarch64 platform.
|
|
|
|
To keep the compatability, this only apply for the RHEL9.6 machine
|
|
type. For RHEL9.4 machine type, it still keep the old Manufacturer and
|
|
Product Name.
