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 m

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 someh

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 releas

Not sure it will help, here is how I'm running it (without an SSD): /usr/bin/acrn-dm -A -m $mem_size -s 0:0,hostbridge \ --lapic_pt \ --rtvm \ --virtio_poll 1000000 \ -U 495ae2e5-2603-4d64-af76-d4bc5a

Hi Geoffroy, gnome-terminal results in the same error, "There was an error creating child process...". In ssh session I see this: Ctrl-alt-f3 works, I can log in. Ctrl-alt-f2 returns me to the GUI, wh

Hi Geoffroy, Please find attached the comparison of /proc/mounts content, left side with ACRN, right side without ACRN but with the same kernel. They're mostly identical, I don't know if smaller diffe

Hi Geoffroy, With ACRN (Terminal doesn't work): /proc/mounts: /dev/pts/*: Without ACRN but with the same kernel (Terminal works), the content is the same. Regards, Dubravko Dubravko Moravski SW engine

Hi Xinjun and Geofrroy, I've made more tests and found a combination of settings where mouse cursor is working well. This doesn't work, kernel starts loading but crashes; I'm not sure what exactly hap

Hi Geoffroy, I've tried your recommendations, they partially work but not quite. I did already have acrn.conf, some tool must have generated it at some point. I have three different situations, depend

Hi Geoffroy, SOS command line parameters are: initrd=\EFI\org.clearlinux\freestanding-00-intel-ucode.cpio initrd=\EFI\org.clearlinux\freestanding-i915-firmware.cpio.xz root=PARTUUID=ef5fabcd-7773-447d

Hi Zide and Geoffroy, Yes, igb i211 driver now works on SOS, and UOS can access the network too, without changing any setting or modifying the kernel. Usually I would suspect some hardware issue, but

Hi Zide, Your advice was helpful again. I have recompiled acrn-dm, edited the launch script, and now UOS works. I'm not exactly sure why, but Ethernet works too! I'm using the same board and the same

Hi everyone, I confirm my ACRN sources did include 65ed6c3529de8b3f3d890e95a7d816afba7bf379 commit. I've tried reverting it - due to the subsequent modifications it wasn't trivial but in the end I've

Hi Zide, Thank you for explaining all the kernel and Ubuntu options. It looks like all the use cases we are interested in are covered. I've got a replacement board and I'm continuing with ACRN. I've f

Hi Zide, I've noticed that for Service OS kernel, you've provided a link to a dedicated repository. I've had a meeting today and was asked to ask the experts on the mailing list to please clarify: Is

Hi Zide, I've managed to download the kernel as instructed, enable the required Ethernet driver, and compile the kernel. Today when I wanted to test it, my board has died, for no particular reason. Ha

Hi Shuo, Thank you, you were right, with your fix ACRN loads the Service OS on my board too. Now I have the issue that Ethernet doesn't work (while it does in regular Clear Linux), so I can't download

Hi Zide, 1) X2APIC I see that it's not mentioned anywhere in ACRN log (and I suppose it should be), but it seems to be enabled somehow in non-hypervised Linux: Our BIOS does not have a GUI setting to

Hi Zide, I've checked all the menus and settings in our BIOS, unfortunately I couldn't find anything that looks like the mentioned setting or similar or related to it. We are using coreboot, built acc

Hello, Please find attached the log file and my acrn.conf. My old BIOS didn't have any settings related to Mwait, so I've installed newer BIOS which has "Monitor Mwait Enable" and I've ensured it's se
