In current rawhide, I get this when attempting to install a new domain with virt-manager. virt-manager-0.6.0-6.fc11.x86_64 kernel-2.6.29-0.25.rc0.git14.fc11.x86_64 Additional Information: Source Context unconfined_u:system_r:qemu_t:s0 Target Context system_u:object_r:ptmx_t:s0 Target Objects ptmx [ chr_file ] Source qemu-kvm Source Path /usr/bin/qemu-kvm Port <Unknown> Host amd Source RPM Packages kvm-81-2.fc11 Target RPM Packages Policy RPM selinux-policy-3.6.2-2.fc11 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name catchall_file Host Name amd Platform Linux amd 2.6.29-0.25.rc0.git14.fc11.x86_64 #1 SMP Sat Jan 10 02:55:41 EST 2009 x86_64 x86_64 Alert Count 2 First Seen Mon Jan 12 15:23:15 2009 Last Seen Mon Jan 12 15:23:40 2009 Local ID 6e5595ff-490b-46de-8fba-cf997edce1f9 Line Numbers Raw Audit Messages node=amd type=AVC msg=audit(1231734220.519:70): avc: denied { read write } for pid=2951 comm="qemu-kvm" name="ptmx" d ev=tmpfs ino=474 scontext=unconfined_u:system_r:qemu_t:s0 tcontext=system_u:object_r:ptmx_t:s0 tclass=chr_file node=amd type=SYSCALL msg=audit(1231734220.519:70): arch=c000003e syscall=2 success=no exit=-13 a0=7fdaf5d0181f a1=2 a2= 0 a3=7ffffe6144f0 items=0 ppid=2836 pid=2951 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) s es=3 comm="qemu-kvm" exe="/usr/bin/qemu-kvm" subj=unconfined_u:system_r:qemu_t:s0 key=(null)
I've just tested this and it appears to work fine in current rawhide, so assuming this was an earlier policy bug. Re-open if it recurrs...
