Re: ACRN hypervisor message: VMX ctrl 0x48b not fully enabled: request 0x18b but get 0x8b

Hi, Joe, Thanks for the update, we will also check from our end. Thanks & Best Regards, Jason Chen SSG -> OTC -> Intel Auto Hypervisor Team

Hi Jason, Eventually I found out the culprit: After removing CONFIG_SERIAL_8250_PNP=y from kernel_config_uefi_sos I have the expected behavior. Thanks, Joe

Hi, Joe, After change vuart irq from 4 to 6, the SOS kernel config need enable CONFIG_SERIAL_8250_DETECT_IRQ, otherwise, the ttyS0 will work under polling mode and slowly… Thanks & Best

Hi Geoffroy & list, Any news on this? On my side the issue is related to the uart being very slow. SystemD messages appears very slowly through the uart. After bisecting a bunch of commit I eventually

Re: ACRN hypervisor message: VMX ctrl 0x48b not fully enabled: request 0x18b but get 0x8b

Hi Geoffroy & list, Same issue here but with an Intel NUC NUC7i5DNHE. After reading ACRN code, it looks like it means there's not support for VMX_PROCBASED_CTLS2_VAPIC_REGS. Is that true? What are the

Re: How to get out of 'vmexit'

@Geoffroy Just confirmed, it is a bug. The vmexit info buffer handling just check the buffer size at the beginning. It need check each time when add info into it. I'll fix

Re: How to get out of 'vmexit'

I'll check that, it could be a bug for the command :(

Re: How to get out of 'vmexit'

Thanks for the confirmation. I will see if I can find a different HW to test with. I have tried a few more times on the NUC7i7DNHE and it consistently get stuck... here is what I

ACRN hypervisor message: VMX ctrl 0x48b not fully enabled: request 0x18b but get 0x8b

Hi folks, When booting ACRN on my KBL NUC (NUC7i7DNHE), I see the following messages on the console: ACRN Hypervisor calibrate_tsc, tsc_khz=2100000 [12273476us][cpu=0][sev=2][seq=9]:HV version

Re: How to get out of 'vmexit'

Re: How to get out of 'vmexit'

Re: How to get out of 'vmexit'

I think you're talking different things. Vmexit command in "hypervisor console" is used to show the info/count which cause vmexit; it is used for debug. Not sure if it is included in our doc. After

Re: How to get out of 'vmexit'

That depends on how you trigger vm-exit. Basically, VMM needs to advance the GIP to mark the end of execution of the guest instruction. Thx Eddie
