RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Newer spice client and agent versions allow copy and pasting from client to guest, but this may not be desirable in all environments. qemu-kvm-0.12.1.2-2.165.el6 adds a new -spice commandline argument "disable-copy-paste" which allows turning off copy and paste support for the virtual machine being started.

Red Hat Product Errata RHSA-2011:1531 0 normal SHIPPED_LIVE Moderate: qemu-kvm security, bug fix, and enhancement update 2011-12-06 01:23:30 UTC

Description Hans de Goede 2011-04-05 07:54:00 UTC 
From a security pov copy and paste between the guest and the client is not
always desirable. So we need to be able to enable/disable this. The best place
to do this from an administration pov is on the hypervisor, and thus on the qemu cmdline.

I already have patches for spice-server to add a function call which will allow the qemu spice code to enable/disable copy paste, see bug 693638. This bug is for getting the qemu bits of this functionality into place.

I've a patch for this which I'll attach.

Talked to Hans via irc

If you want to test it via qemu-kvm, please add options disable-copy-paste and newer spice-server

-spice port=5932,disable-ticketing,disable-copy-paste
Comment 10 Qunfang Zhang 2011-09-06 02:02:44 UTC 
Tested on qemu-kvm-0.12.1.2-2.160.el6, there's no "disable-copy-paste" spice 
option.
Boot with "disable-copy-paste" spice option, QEMU prompts: 
qemu-kvm: -spice port=5930,disable-ticketing,disable-copy-paste: Invalid parameter 'disable-copy-paste'
parse error: port=5930,disable-ticketing,disable-copy-paste

Verified passed on qemu-kvm-0.12.1.2-2.184.el6.
1. Boot RHEL6.2&win7 guest with the following command:

/usr/libexec/qemu-kvm -M rhel6.2.0 -cpu cpu64-rhel6,+x2apic -enable-kvm -m 2048 -smp 2,sockets=2,cores=1,threads=1 -name RHEL6.2-64 -uuid 2b379603-6f73-497c-bbdc-d3dc948248e8 -monitor stdio -rtc base=localtime -boot c -device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x4 -drive file=/home/win7-32-virtio.qcow2,if=none,id=ide-drive-0,format=qcow2,cache=none,werror=stop,rerror=stop -device ide-drive,bus=ide.0,unit=0,drive=ide-drive-0,id=ide0 -netdev tap,id=hostnet0,script=/etc/qemu-ifup -device e1000,netdev=hostnet0,id=net0,mac=00:1a:4a:10:84:09,bus=pci.0,addr=0x3 -chardev socket,id=charchannel0,path=/tmp/foo,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.rhevm.vdsm -chardev spicevmc,id=charchannel1,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=com.redhat.spice.0 -usb -spice port=5930,disable-ticketing,disable-copy-paste -k en-us -vga qxl -global qxl-vga.vram_size=67108864

2. Install qxl driver, spice vdagent, and virtio-serial (win) driver inside guest. 

3.Copy-paste some string between external host and guest, failed. Can not copy-paste.

4.Shutdown guest, boot guest again while removing "disable-copy-paste" option.

5.Copy-paste some string between external host and guest, succeed. The content is well copied and pasted.

So, this issue is verified pass.
