Hi Dubravko, For SOS kernel, I suppose you could build it based on our acrn-kernel with igb enabled. It looks like the serial port is a little bit mess. From dmesg_nohv.log, we could see following

Hi everyone, We've been busy bringing up some new hardware so it took me some time to respond. We are very grateful for all the assistance. I have uploaded the requested new logs to

Hello, I'm completely new to ACRN (only having learned about it yesterday). Let me know if this is not the proper group to post this question to. Should ACRN support any OS or does the OS require

Hi Dubravko, The UP2 board uses realtek network controller. I believe the reason that your network can't work is the network controller is not enabled in SOS kernel. Could you please find out the

Hi Dubravko, I only see following message from your sos kernel log: [ 1.200862] ixgbevf: Intel(R) 10 Gigabit PCI Express Virtual Function Network Driver - version 4.1.0-k [ 1.201695] ixgbevf:

Hi Dubravko, Which ttyS is used for console depends on your hardware design. You need to check with your hardware engineer to figure out which ttyS is used for console. If you are using the UP2

Hi Conghui, Yes. Emulated ttyS0 and physical ttyS1 share same irq. But there is no user of ttyS1. we can't see ttyS0/ttyS1 share irq4 in interrupt dump. But as Anthony said, the emulated ttyS0 share

Hi Dubravko， Checkedifconfig_log_20190913.log you uploaded: acrn-br0 Link encap:Ethernet HWaddr F2:14:63:23:6B:FD inet6 addr: fe80::f014:63ff:fe23:6bfd/64 Scope:Link

Hi, I have tried: compiling ACRN release version and setting console=ttyS2 (an earlier suggestion) = no improvement using ACRN release version and removing console=ttySx setting = the system is

Hi Dubravko, In SOS, vuart is sharing irq 4 with idma, that may cause issue. I think you are using debug version, can you try release version? There is no ttyS0 in release version. And please

I mean removing both hvlog=2M@0x1FE00000 and memmap=2M$0x1FE00000, that disables HV log. We can make hvlog optional, if hvlog is not specified, acrn log driver should allocate sbuf just like acrn

“memmap=2M$0x1FE00000” will reserve the memory for HV log; There is stability issue if no this parameter in cmdline(memory used by kernel was overwrite by HV log); Fengwei can give more detail

“memmap=2M$0x1FE00000” SOS kernel parameter is platform specific, can we remove “memmap=2M$0x1FE00000” by default? The only usage of “memmap=2M$0x1FE00000” is to check crack log,

Hi Geoffroy, I have already tried with uart=disabled, and repeated the test now; everything remains the same, all the issues are present. SSH works when not running in the hypervisor. I'm using the

Hi Dubravko,

Hi Dubravko, Can you try to use /dev/ttyS2 as SOS console? Replace the “console=ttyS0” in acrn.conf with “console=ttyS2”. Regards, Conghui.

Hi everyone, SOS console/terminal can't be opened at all; the window actually opens but it says"There was an error creating a child process for this terminal. Failed to open PTY: Permission denied"

Hi Fengwei, It seems irq 4 is shared between two uarts. For ttyS0, it's interrupt is default as 4, and it is correct in the log. [ 1.084989] serial8250: ttyS0 at I/O 0x3f8 (irq = 4, base_baud =
