[Xen-devel] XEN 3.4 and blktapctrl

[VM-Sascha <sascha@xxxxxxx>]

Hello all, 

i'm playing with the new XEN 3.4 and if i use the backend "tap:aio" on my
domUs, all have the same
tapctrlwriteX & tapctrlreadX fifos

<SNIP>

tapdisk /var/run/tap/tapctrlwrite312222 /var/run/tap/tapctrlread312222
tapdisk /var/run/tap/tapctrlwrite312222 /var/run/tap/tapctrlread312222
tapdisk /var/run/tap/tapctrlwrite312222 /var/run/tap/tapctrlread312222
tapdisk /var/run/tap/tapctrlwrite312222 /var/run/tap/tapctrlread312222

</SNIP>

On XEN 3.3.1 it was always the domid like this:

<SNIP>

tapdisk /var/run/tap/tapctrlwrite1 /var/run/tap/tapctrlread1
tapdisk /var/run/tap/tapctrlwrite2 /var/run/tap/tapctrlread2
tapdisk /var/run/tap/tapctrlwrite3 /var/run/tap/tapctrlread3
tapdisk /var/run/tap/tapctrlwrite4 /var/run/tap/tapctrlread4

</SNIP>

Has anyone an idea why this happens on the new release?

Thanks,
Sascha
