I have attached dmesg output from the sos. Cheers Steve -- Engineering Director IOTech Systems Ltd.

Hi Steve, It looks like the physical UART is used by HV and SOS at the same time. Per my experience, it's not possible if the UART port is legacy UART. Could you please ssh to your SOS and dump the

Hi Steve, It’s weird. My minicom setting: 115200 8n1, no HW flow control, no SW flow control. Then another approach is you can patch hypervisor as follows, then it should be able to print

Hi Steve, It is strange. Could it be related to your input method? My experience, if I am using Chinese input method, ctrl + space will not work to switch to hypervisor console.

Hi Binbin, Problem is that ctrl + space doesn't switch to hypervisor, if I press return multiple times, occasionally I get the hypervisor prompt, but if I then enter anything is passed to the

Hi Steve, If you see the below notation ACRN:\> It means you have switched to hypervisor console. You can set hypervisor

Hi Binbin, Ctrl + space does not appear to work (have tried with both minicom and gtkterm clients). However sometimes looks like serial console is being multiplexed between both sos and

Hi Dubravko, Great to hear that! -- BRs, Binbin

Hi Binbin and Zide, Thank you, I confirm that this works very well, and we've got acceptably low latencies in RTVM. Actually my colleague with better understanding of the test has commented that new

Hi Steve, You can switch to hypervisor console using “ctrl + space” If you want to switch back to sos console, type “vm_console 0” -- BRs, Binbin

Hi Zide, Vave verified that the RTVM uuid is correct in vm_configurations.c. Sorry if this is a silly question, but am getting logging from the SOS on my serial console, how do I just get hypervisor

Hi Dubravko, For the device related to RT performance, it needs to passthrough the device to RTVM to avoid VM-Exits. To passthrough the ethernet card to RTVM, you can refer to the sample launch

Hi Dubravko, I think you can do it by passthru the PCIe network adapter to UOS, just like what you did to passthru any other devices. You may further remove those acrn-br0 and tap devices by

Hello, We might have figured out one way to get improved network performance in UOS, but after googling and checking ACRN documentation I'm still not sure whether it is actually possible: can we

Hi Steve, It failed at the CREATE_VM hypercall handler in hypervisor (hcall_create_vm()), but I expect some error messages from hypervisor telling why it failed. Are you sure the hypervisor

Hello, We want to use ACRN to, among other things, "talk" to Ethercat PLCs. Without ACRN, we get latencies of about 500 us. Acceptable latencies are generally below 1 ms. With ACRN (compiled in

Hi Geoffroy, Output is via a serial connection to GtkTerm on Ubuntu. Output doesn't seem to wrap well and generally "gets confused, not sure why. Cheers Steve -- Engineering Director IOTech Systems

From SOS: # cat /proc/cmdline initrd=\EFI\org.clearlinux\freestanding-00-intel-ucode.cpio initrd=\EFI\org.clearlinux\freestanding-i915-firmware.cpio.xz

Out of curiosity: do we know what can cause many random characters to be dropped in the error message below? Is the system heavily loaded? Thanks, Geoffroy
