Hi, I'm currently facing problems to get kvm working with -no-kvm-irqchip. It used to be fine up to kvm-71, but with latest git my Linux guest stalls during early boot: [ 22.631200] Freeing unused kernel memory: 324k freed [ 22.857098] SCSI subsystem initialized [ 22.892601] scsi0 : ata_piix [ 22.903604] scsi1 : ata_piix [ 22.904473] ata1: PATA max MWDMA2 cmd 0x00000000000101f0 ctl 0x00000000000103f6 bmdma 0x000000000001c000 irq 14 [ 22.917692] ata2: PATA max MWDMA2 cmd 0x0000000000010170 ctl 0x0000000000010376 bmdma 0x000000000001c008 irq 15 This seems to be a kernel-side issue, replacing the module set with the one that came with -71 fixes the issue. Maybe due to vmx_complete_interrupts refactoring? Jan
