Christopher,
since commit 20a83313ea74283edfe5c000dd7d3e888e61a717, the data.tar that Burak
attached in his original post fails to generate a config. Same is true for the
config Chung-Fan Yang posted earlier in another thread. It seems the refactoring
came with a subtle regression...

Hello everyone,
I am encountering some problems while trying to run Jailhouse. Attached you can
find the sysconfig file that was generated by “jailhouse config create” command.
While I was cross-checking the memory regions in the sysconfig file with the
output from “cat /proc/iomem” I realized that there was a missing memory region,
so I had to manually enter the following to the sysconfig file:
/* MemRegion: 796b9000-79887fff : Reserved APEI ERST
{
.phys_start = 0x796b9000,
.virt_start = 0x796b9000,
.size = 0x1cf000,
.flags = JAILHOUSE_MEM_READ |
JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_EXECUTE |
JAILHOUSE_MEM_DMA,
},
Before this configuration, “jailhouse enable” command would crash the machine,
after this modification when I run Jailhouse I get the following error:
Activating Hypervisor
VT-d fault event reported by IOMMU 0:
Source Identifier (bus:dev.func): 03:00.0
Fault Reason 0x26 Fault Info: 49000000000 Type 0
I studied the source code for Jailhouse, and also tried to find a solution in
the mailing list, but I was unable to do so. I am attaching the output of the
command “lspci –vvv –s 03:00.0”, “jailhouse hardware check”, “cat /proc/iomem”,
and the system information that is collected by “tools/jailhouse config collect
data.tar”.
Any suggestions are welcome.
Best regards,
Burak Atalay
