That was indeed the issue, so thank you very much for the quick response! I'm now facing the next problem:
Adding virtual PCI device 00:0c.0 to cell "linux-x86-demo" Adding virtual PCI device 00:0d.0 to cell "linux-x86-demo" Adding virtual PCI device 00:0e.0 to cell "linux-x86-demo" Adding virtual PCI device 00:0f.0 to cell "linux-x86-demo" Created cell "linux-x86-demo" Page pool usage after cell creation: mem 375/975, remap 16395/131072 Cell "linux-x86-demo" can be loaded CPU 2 received SIPI, vector 100 CPU 3 received SIPI, vector 100 Started cell "linux-x86-demo" FATAL: xAPIC access in x2APIC mode FATAL: Unhandled APIC access, qualification 20 RIP: 0xffffffff81649d42 RSP: 0xffffffff82a03e98 FLAGS: 10046 RAX: 0xffffffff81649d40 RBX: 0x000000000479f000 RCX: 0x0000000002410067 RDX: 0xffffffff82fbc796 RSI: 0xffff9de180000000 RDI: 0x0000000000000020 CS: 10 BASE: 0x0000000000000000 AR-BYTES: a09b EFER.LMA 1 CR0: 0x0000000080050033 CR3: 0x000000000240a000 CR4: 0x00000000000626b0 EFER: 0x0000000000000d01 Parking CPU 2 (Cell: "linux-x86-demo") >From what I can gather from the source code, my system is able to use the faster x2APIC mode (programmed using MSRs), but Jailhouse is trying to perform MMIO accesses which are only possible in legacy xAPIC mode. Is there a guide somewhere that documents the steps necessary for adjusting the linux-x86-demo cell config? Am Freitag, 14.
