Hi Rajesh, I saw the following XML configuration in your case-1-virsh_attach_device_first.log.txt, what's "#012"? it seems you copy-paste it from a web, please remove it from XML then attach it again. virDomainAttachDevice:9235 : dom=0x6b20a0, (VM: name=new-installed, uuid=6122cebb-e33c-a66a-9b71-a0047c91d7bb), xml= <hostdev mode='subsystem' type='pci' managed='yes'>#012 <source>#012 <address domain='0x0000' bus='0x04' slot='0x10' function='0x0'/>#012 </source>#012 <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>#012 </hostdev>#012 In addition, I tried to assign/unassign a normal NICs to/from the running guest with managed='yes' again, indeed, the NICs hasn't been returned to host with 'managed' mode although virsh said "Device detached successfully", I must to stop the guest then manually return the NICs device to host via 'virsh nodedev-reattach pci_$domain_$bus_$slot_$function' such as virsh nodedev-reattach pci_0000_04_10_0, here is a similar bug "https://bugzilla.redhat.com/show_bug.cgi?id=843016";. BTW, rhel6.2 isn't necessary, it should work for other platform such as fedora, centos, etc. -- Regards, Alex ----- Original Message ----- From: "Rajesh Kumar Mallah" <mallah@xxxxxxxxxxxxxx> To: "Alex Jia" <ajia@xxxxxxxxxx> Cc: libvirt-users@xxxxxxxxxx, "vikas pandey" <vikas_pandey@xxxxxxxxxxxxxx> Sent: Monday, August 27, 2012 4:18:01 PM Subject: Re: automatically detaching PCI host devices from guest for SRIOV usage. Dear Alex , What do you have in the Host ? Does the guests behave as we are expecting them to behave in our setup ? <offtopic> can i get rhel6.2 for trying? </offtopic> Also i have attached the files this time.
