Hi
I’m currently having some trouble installing Qubes OS. I’m trying to install Qubes R4.0.4 on a Legion 5 15arh05h (not listed on HCL) with AMD Ryzen 7 4800h and Nvidia Geforce 1660Ti, with AMD-V (SVM) enabled.
At first I was getting the “Not asking for VNC because we don’t have a network” / “X startup failed, aborting installation” / “Pane is dead” error on UEFI during installation. I verified the integrity of the ISO and tried making a USB stick using both rufus and dd method and switched to legacy boot mode and tried but I kept getting stuck on a black screen. I tried the solutions mentioned here, but none of them worked, then I tried the “Install Qubes R4.0.4 in basic graphics mode” under troubleshooting menu and it got me further. I’m now getting the following error:
“(XEN) Not responding”
“(XEN) Failed to bring up CPU i (error -5)”
It prints it for all the available threads of CPU (i from 1 to 16), indicating that the installer cannot successfully boot up the cpu cores. I looked it up but no topics came up. I was however able to find it in the github source codes of Xen, in case it might help with the troubleshooting somehow. it is apparently generated by /xen/arch/x86/setup.c which prints the return value of cpu_up():
which gets its value from either cpu_notifier_call_chain() or __cpu_up(), but based on the 5 second delays I’m getting between each error line and the error code which is -5, which based on the errorno.h translated to I/O error (in ARM version it is explicitly returns -EIO, which is -5), I’m guessing it is generated by __cpu_up().
Any ideas on what’s causing the problem and how to solve it?
Update: I have tried the workaround mentioned here for AMD APUs that have a similar problem with XEN installers by setting maximum memory of dom0 to 2048M and it didn’t help solve the problem either.
Thanks
