Description: Modifying emulated devices' virtual queue or MSI-X number to exceed the total number (summation of all emulated devices' virtual queue or MSI-X number) of 4K would cause assert with ext_synd 0x80d8 in dmesg, and some virtual queue not to functional. |
|
Workaround: Set the virtual queue or MSI-X lower than 4K as the total number limitation. |
