Public bug reported:
Since upgrading from 4.2 to 5.0, a Windows XP VM takes much longer to
boot.
It hangs about three minutes on "welcome" screen with the blue
background, while previously the total boot time was less than a minute.
The issue only happens in TCG mode (not with KVM) and also happens with
the current master which includes the uring patches (7d3660e7).
I can reproduce this issue with a clean XP install with no flags other
than `-m 2G`. After booting, the performance seems to be normal.
