LVM volume group shared between KVM/libvirt host and guests: is this a bad idea? Also, I am staying with Method 1 for now because I think it would be educational to explore the limitations of this method. For example, I learnt that if in a guest OS you create an LVM PG directly onto the device (eg. device /dev/vda instead of partition /dev/vda1), then the host OS' pvscan lists the guest's PV (ie. use /dev/vda1, not /dev/vda). |

LVM volume group shared between KVM/libvirt host and guests: is this a bad idea? Thanks everyone for your answers, all have been helpful to me and it was hard to choose whose answer to accept. I am choosing Steven's because I feel it makes the best effort to address the question asked. For the record, while I agree Method 2 is probably better, I chose to stay with Method 1 because it works and because of time constraints. |

LVM volume group shared between KVM/libvirt host and guests: is this a bad idea? when I do an "lvscan" on the host OS, it reports the guest's LV as "ACTIVE". The host does not have the LV mounted. Does the LV simply being in "ACTIVE" state constitute a "read/write mode", or do you mean an explicit mount to the host's filesystem? |

LVM volume group shared between KVM/libvirt host and guests: is this a bad idea? thanks. I have appended 2 updates to my question, which further explain why I have listed some of the cons that you have addressed. Do the updates change your opinion at all? |

Virtualisation server for a small business: questions on design, hardware components and vendor ps. 1) I know the RAM is low, but the board can take another 8GB if need be. 2) I chose the RE3 HDDs because they are apparently designed for high load use. 3) The boss said if we need a faster system, he is happy for me to convert this one into a desktop and then buy a proper server. |

Virtualisation server for a small business: questions on design, hardware components and vendor Well TomTom, the boss has opted that we just get a basic desktop-class server up and running for now. I have just purchased parts for a Phenom II X4-based system: Phenom II 955 X4 Black Edition processor, 2x4GB Kingston PC3-10600 DDR3 RAM, Gigabyte GA-880GM-USB3 motherboard, 4x WD Caviar RE3 500GB SATA II HDDs, Antec BP500U Basiq 500W ATX power supply, CoolerMaster CM 690 case. I am going to accept your answer since a) my question was probably too complex as previously mentioned, and b) you reminded me that AMD-based systems can be cost-effective. Thanks! |

Virtualisation server for a small business: questions on design, hardware components and vendor I'm wondering if it is realistic to expect someone to be able to completely answer this question. I was thinking that I should have posted it as separate SF questions, but I opted for an all-in-one so that the reader would have a reasonable level of context with regard to the situation. |

Virtualisation server for a small business: questions on design, hardware components and vendor Thanks, TomTom, I will take a look at your recommendations. I would love to get SAS for high IOPS but it seems a little expensive? I only mentioned SAN because that is likely the future direction for this setup in terms of adding redundancy (more servers, with live migration of VMs). In the meantime, I can look at ensuring that the case/backplane has spare bays for extra DAS drives. I am curious why you say the RAM is a bottleneck, as I can always add more to this server (which is part of the reason I chose RDIMMs as opposed to UDIMMs). [ps. sorry for the late response as I have been on leave] |
