In the end of virConnectGetVersion() description there is written: "not with a Read-Only connection" which isn't true after I tried virConnectOpenReadOnly() with virConnectGetVersion() and it clearly shows the version correctly.
It seems this was true originally at the time of introduction in:
commit 96a54b42a64ffff90beaec2b7d5e883888c7c11b
CommitDate: 2005-12-08 13:26:52 +0000
* src/libvir.c src/libvir_sym.version src/xen_internal.[ch]
include/libvir.h: implementing hypervisor Version and Type interfaces
But then the ioctl getting the version was moved to the time of
initialization of the xend driver:
commit a2e2e4652f29c7acddec37c0b0f46c1179895d0e
CommitDate: 2006-06-21 12:15:18 +0000
* src/xen_internal.c: try to autodetect the Xen hypervisor version
used and switch automatically. A bit nasty though.
( And the whole xend driver was removed in 2018 by commit 1dac5fbbbb )
