Dear All I try to migration a kvm guest os to another host failed server: ubuntu 11.04 server virsh:migrate --live --tunnelled vm1 qemu+ssh://192.168.10.3/system error:Requested operation is not valid:cannot perform tunnelled migration without using peer2peer flag

Hi, I'm experimenting with the migration function of virsh. I'm doing the migrate with following commands: virsh migrate --life --persistent --copy-storage-all --verbose --abort-on-error domain qemu+ssh://root@destination/system virsh migrate-setmaxdowntime domain 20000 However sometimes at the end of the migration, the guest isn't started on the destination host. So I'm left

Hi, when I try to use such API: virDomainPtr <http://www.libvirt.org/html/libvirt-libvirt.html#virDomainPtr> virDomainMigrate (virDomainPtr <http://www.libvirt.org/html/libvirt-libvirt.html#virDomainPtr> domain, virConnectPtr <http://www.libvirt.org/html/libvirt-libvirt.html#virConnectPtr> dconn, unsigned long flags, const char * dname, const char * uri,

...swords, I still get this error message. My question, is it possible to even allow Linux2Linux network sharing with Samba? Everything out there is geared for Windows2Linux. If it is possible what would I have to do to my smb.conf file to enable this? I am really trying to get away from Windows and peer2peer networking is my biggest hang-up. Thank you for reading my email. russell pardo

Hello every body: I have RedHat fedora core 2 machine, using iptables and squid. I am having a lot of problems with peer2peer traffic. (bittorrent, kazaa, etc.) so I have installed ipp2p from rpm. Every thing was ok until I use iptables rules. I get this error. [root@router iptables]# iptables -A INPUT -p tcp -m ipp2p --ipp2p -j DROP iptables: No chain/target/match by that name sames as: iptables -A FORWARD -m ip...

...at least for AMD. AMD still has hardware support in all of their MI* products, but for Navi the features necessary for implementing HMM have been dropped. And it looks more and more like their are not going to come back. Additional to that from the software side Felix summarized it in the HMM peer2peer discussion thread recently quite well. A buffer object based approach is not only simpler to handle, but also performant vise multiple magnitudes faster. > I'm also not into looking at use-cases that used to be important but > might not as important going forward.

Hey, Over in KubeVirt we're investigating a use case where we'd like to perform a live migration within a network namespace that does not provide libvirtd with network access. In this scenario we would like to perform a live migration by proxying the migration through a unix socket to a process in another network namespace that does have network access. That external process would live

...est of the company. So, I want to limit traffic to the Internet, but the traffic to the other class C won''t be limited. Also another requirement is to limit all the day traffic like Morpheus, Kazaa, and stuff like that. The traffic should look like: internal to the company, no restriction. Peer2Peer traffic, 100Kbit day, 60Kbit in the night, Rest of the traffic not limited in the day, 160Kbit in the night. Also, if possible, traffic from the outside shouldn''t be disturbed at all, any time (handled by root class). If I set the 130 class, without the TIME parameter, it won''...

...cate the uuid sounds fine. Then synchronization is entirely up to the virtio subsystem and not a dma-buf problem (and hence not mine). You can use dma_resv_lock or so, but no need to. But with callbacks potentially going both ways things always get a bit interesting wrt locking - this is what makes peer2peer dma-buf so painful right now. Hence I'd like to avoid that if needed, at least at the dma-buf level. virtio code I don't mind what you do there :-) Cheers, Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch

I am trying to work out what all the options are for migrating a KVM machine to another KVM machine, without using shared storage. The documentation is not quite verbose and not intuitive, so I'm hoping someone can explain this to me. The man pages show this syntax: migrate optional --live --p2p --direct --tunnelled --persistent --undefinesource --suspend --copy-storage-all --copy-storage-inc
