Hi there!
Playing around dfly in qemu-kvm and see strange behavior with sata.
I have to identical virt-machines on one hardware host. The only
difference is that one virtual machine emulated sata and another "uses"
ide disk.
In dmesg of "sata"-machine appears:
------------
ahci0.0: CMD TIMEOUT state=5 slot=9
glb-status 0x00000000
cmd-reg 0xc017<CR,FR,FRE,POD,SUD,ST>
port_status 0x4<DSS>
sactive=00000200 active=00000000 expired=00000000
sact=00000000 ci=00000000
STS=50
ahci0.0: disk_rw: timeout
ahci0.0: CMD TIMEOUT state=5 slot=6
glb-status 0x00000000
cmd-reg 0xc017<CR,FR,FRE,POD,SUD,ST>
port_status 0x4<DSS>
sactive=00000040 active=00000000 expired=00000000
sact=00000000 ci=00000000
STS=50
----------
and so on.
Hardware host seems to be fine - several machines work nice, some of
them uses "sata" but OS is linux.
