similar to: How to get VM IP address through XenStore

Hi : As I want to know the information of the VMs that currently runing on the same physical machine, I''d like to get those VM''s information from xenstore, such as macaddress. Indeed, what I want is IP address, so, if guest can write things to xenstore, I''d like it write its IP address into xenstore and let domain0 reads it directly. So, can anybody tell me whether a PV

Hello, When start a domU through xl create. The domU associated ip in the configuration file is not recorded in the xenstore. For this reason vif-common.sh antispoof scripts fails. *xl create * /usr/bin/xenstore-ls /local/domain/0/backend/vif/5/0 frontend = "/local/domain/5/device/vif/0" frontend-id = "5" online = "1" state = "4" script =

Hi, I am trying to find out the IP address of the KVM guest virtual machine. #virsh dumpxml newsoftlinedrupalpoc | grep "mac address" | awk -F\' '{ print $2}' 52:54:00:2c:7e:ff [root@baseserver1 ~]# arp -an | grep 52:54:00:2c:7e:ff [root@baseserver1 ~]# virsh domifaddr newsoftlinedrupalpoc Name MAC address Protocol Address

Package: xcp-xapi Version: 1.3.2-6 Severity: important Tags: upstream xe vm-memory-target-set does not write new target to /local/domain/ID/memory/target. Balloon in guest domain is expecting this value to be changed to do selfballooning. This breaks 'dynamic memory control' feature. Steps to reproduce: 1) Setup any PV virtual machine with static-memory-min < static-memory-max 2)

Hi, $subject says pretty much all, this patch updates netfront and makes it store the network addresses of the interfaces in xenstore, so it''s much easier to figure what IP some virtual machine has and (for example) ssh into it. comments?

Hi, I believe I can post this here. I have a domU ( Redhat 6) running in Paravirt mode. When I migrate this domU to another host, looks like the domU is freezing in the other host. When I take it back to original host ,it starts to run normally and this is what can see in dmesg of domU : suspending xenstore... trying to map vcpu_info 0 at ffff88000434b020, mfn b67660, offset 32 cpu 0 using

Hi,     I am tring to write xenstore some information ,so that a guest can read, if i simply xenstore-write /foo "123" in domain 0, guest have not the permission to read this ,and guest domain number are dynamic, so i can not write a program to write /local/domain/X, which X is the domain id i want to export information to, can i ?     So, is there a path (a static path,without domain

Hi All, Having an issue with xen-4.0-unstable where after completing a live migration, an arp is never sent out to update the switch with the new location of the mac address. Network is configured as per libvirt''s instructions with the xen network-script disabled and the bridge (xenbr0) always up.

Is it possible to create a custom directory tree inside Xenstore using any of the Xenstore-utilities?? For example, "/local/domain/0/Customdir". Thx, Venkat _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, is it possible to access xenstore through libvirt? Or at least any other programatic means other than calling xenstore-read/write through shell? I understand it is somewhat of a security risk but still... Thanks, Marin

Hi,     I use follow code get xenstore ring and event channel, then i wrapped writing and reading function to operate it ,but it came to oops:     struct xenstore_domain_interface {     char req[XENSTORE_RING_SIZE]; /* Requests to xenstore daemon. */     char rsp[XENSTORE_RING_SIZE]; /* Replies and async watch events. */     XENSTORE_RING_IDX req_cons, req_prod;     XENSTORE_RING_IDX rsp_cons,

Hi, I want to know how everything communicates with XenStore. Do domUs use the front-end/back-end driver to dom0 and then the back-end driver contacts xenstored? In particular, how do the xenstore-* commands work on a dom0 and domU? And when should unix-domain sockets be used to communicate with xenstored? Thanks, Hayawardh _______________________________________________ Xen-users mailing

Hi, Can anyone please tell me how to get ".probe" function in "struct xenbus_driver" called? I want to do one simple test of event channel communication between peer modules of domU and dom0. I wrote one backend and one frontend driver (I tried registered as misc/blk/input device) where I put in all my xenbus routines, but cannot get .probe called after insmod my module, I

Hello, I noticed a strace delay when running "virsh list" on my Xen-4.1.3 test server. On further investigation I noticed that in XenStore there were multiple /vm/$UUID entries suffixed by -$VERSION, especially I hat 16 entries for my dom0. For each reboot of the host I get a new entry. After disabling Xend I get the following output after a reboot: > root at xen5:~# xenstore-ls

I understand that "xenstore-chmod XENSTOREPATH perm" will allow xenstore access to each other domains according to the permissions set. But if I need to permit access to a specific domain which will avoid a global permit access, is there a way?
