losetup -a shows

/dev/loop0: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop1: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop2: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop3: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop4: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop5: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop6: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
/dev/loop7: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256

and

losetup -d /dev/loop0

etc. gets rid of them, mount works again. What is still a mystery is
why all these loop devices were set up.
