The 32 bit tests do not have relocation support and rely on the build system to set the text base address to 0x4001_0000, which is the memory location where the test is placed by qemu. However, kvmtool loads a payload at a different address, 0x8000_8000, when loading a test with --kernel. When using --firmware, the default is 0x8000_0000, but that can be changed with the --firmware-address comand line option. When 32 bit tests are configured to run under kvmtool, set the text base address to 0x8000_8000.
